The question seems specifically for films directed by Feroz Khan as Lata had rendered songs in Feroz Khan starrers like Raat Aur Din, Geeta Mera Naam, Teesra Kaun, Unche Log, Upasna etc.
Feroz Khan directed two films in the 70s decade, Apradh and Dharmatma. Lata rendered one song each in both the films. In the 80s decade Feroz Khan directed Qurbani, Jaanbaaz and Dayavan. Lata was not the primary choice for Qurbani & Jaanbaaz, as Feroz wanted a more western disco-pop and contemporary sound that broke away from traditional Bollywood melodies.
That’s the reason he used Nazia Hasan for “Aap Jaisa Koi” in Qurbani and Kanchan for “Laila Main Laila”. A young breathy non-classical western timbre to match the modern aesthetics.
Even Asha Bhosle just had one number in Qurbani (Kya Dekhte Ho), though she was known for her seductive voice and her vocal delivery was synonymous with the glamourous “modern woman” in Indian cinema.
Till the time Dayavan was released, the industry was actively exploring new younger vocal textures for its on-screen actresses. This was the time from when Kalyanji-Anandji was replaced with other music directors in all Feroz Khan films thereafter.
The result, Dayavan, Yalgaar and Prem Aggan had a mixture of Kavita Krishnamurthy, Sapna Mukherjee, Saadhna Sargam, Alka Yagnik and Anuradha Paudwal while Sunidhi Chauhan and Jaspinder Narula were the new voices used for Janasheen.
He was considered one of the most handsomest actors ever . His good looks rivalled that of Dharmendra's
He had thick wavy hair in his youth
& Went bald in his later years
One of the few actors who didn't go for weird unnatural wigs
He came from Bangalore his brother Sanjay Khan was also a very successful actor
He had done a lot of movies like Didi, Ghar Ki Laaj,Tarzan but he got his first taste of recognition with Oonche Log in 1965
The movie that made Jeetendra a star was first offered to Feroz Khan.
Farz
Even the movie which started the famous Amitabh Bachchan and Vinod Khanna jodi
Hera Pheri was first offered to Feroz Khan
But Khan wasn't interested in doing alot of movies
When the likes of Jeetendra and Mithun Chakraborty have 200 and 300 movies respectively Feroz Khan only did 50 to 60 odd movies.
Feroz Khan was a tall man in his youth somewhere between 5′11 and 6′0 little shorter than Amitabh Bachchan and as Tall as Sanjay Dutt
It's said it was Feroz Khan who introduced Sanjay Dutt to the underworld
& Feroz Khan and his friend Vinod Khanna died in the same day albiet different years
Feroz Khan's career started gaining pace in the later 60s when he did 2nd leads in movies like Aadmi Aur Insaan
Safar
Mela
But he wasn't as successful as his younger brother and reigning superstar Rajesh Khanna
Hence turned his attentions towards production and direction
He directed the moderately successful Apradh in 1974 with Mumtaaz
And wanted to make an indianised version of The Godfather with Rajesh Khanna
Which ultimately became Dharmatma originally he wanted to play the supporting role of Danny Denzongpa and Direct the movie bit Rajesh Khanna vetoed that decision and told Feroz Khan to focus only a director this move changed the careers of three people Rajesh Khanna who after losing Deewar could've restablished himself as an action hero, Danny Denzongpa who became a sought after villain & Feroz Khan who himself became a huge star
He Feroz Khan after Dharmatma zoomed past his brother in Stardom and had the meatier role of the two in Naagin after playing supporting role in the earlier Mela
Feroz Khan gave the biggest hit of the 1980 Qurbani
Which became a much bigger hit than the most anticipated movie Shaan
& Surprise blockbuster Aasha
The success of Qurbani was so huge that it steamrolled a very well made movie like Karz
Later on Feroz Khan kept acting in also Ran movies like Chunouti with Dharmendra
Khoon Aur Paani with Jeetendra
I think he could've been a huge success in movies like Himmatwala,Mawaali,Tohfa,Qaidi and Justice Chowdhury has he decided to continue acting
Feroz Khan later started acting a deutragonist in his movies like Jaanbaaz and Dayawan While Jaanbaaz was a huge hit
Dayawan was a moderate success
based loosely on the likes of Vardharajan Murlidhar . Once Akshaye Khanna even said that it was his favourite movie of his father
Vinod Khanna in Dayawan
Feroz Khan’s career lantern took a backseat after the launch of his Son
With whom his movies didn't work
I feel had Fardeen Khan not tried to become a diluted version of Salman Khan and Shah Rukh Khan respectively and followed in the footsteps of his dad he could've succeeded
Feroz Khan was one of the first Indian actors to openly keep a Muslim name in an era when Yousuf Khan became Dilip Kumar, Mahjabin Bano became Madhubala
However Feroz Khan wasn't his orginal name his real name was Zulfiqar Shah Ali Khan.
A thorough patriot who criticized Pakistan and it's government in Pakistan nonetheless
Feroz Khan has his fair share of fights in the India with the likes of Shammi Kapoor
He was one of the only actors who took down the wild sided Sanjay Dutt
He even has a huge fight with SRK who rejected his movie
I think SRK always wanted to be an action hero a Feroz Khan movie in the initial stage of his career would've helped him but similar to Rajesh Khanna SRK also rejected Feroz Khan
Feroz Khan launched and relaunched several actors like Danny Denzongpa and Shakti Kapoor who became premier villains after his movies Dharmatma and Qurbani
Feroz Khan also relaunched Dimple Kapadia as a leading actress after a her failed marriage to Rajesh Khanna
Similarly Vinod Khanna's comeback to Bollywood was with Dayavaan one of the few movies where he shed his commerical action hero portrayals and totally becoming the character to get rave reviews
It's sad that he couldn't make his son a huge star
Feroz Khan was called Clint Eastwood of the east due to his uncanny resemblance to the former
Even the all time blockbuster Sholay
Was inspired by a Feroz Khan spaghetti western Khotte Sikkay
It's said he used to shuffle in the streets of Bombay as a cowboy as told by Shakti Kapoor
Feroz Khan brought in alot of elements into bollywood like Race car driving in Apradh
Later used in Baazigar
Feroz Khan popularized western attire in actresses
And motorcycles in Bollywood
When every actor from Amitabh Bachchan, Rajesh Khanna, Mithun Chakraborty, Jackie Shroff opted for wigs and hair patch
Feroz Khan happily flaunted his slick chrome
The supremely successful Welcome was his last movie
Feroz Khan or Khansaab as he was called loved his life king size on his own terms as Nana Patekar say’s
