In the recent released Ramayana movie (Namit Malhotra’s) there are many mistakes.
First: There is no mention of Sita Swayamvar in the original Valmiki Ramayana but not only in recent Ramayana but almost all earlier Ramayana movies and web series have shown the Sita Swayamvar.
Second: There is no mention of Lakshman Rekha in the original Valmiki Ramayana but it is shown in the Namita Malhotra’s Ramayana movie. In the original Valmiki Ramayana, Sita start cursing Lakshman and did his character assassination and in anger, Lakshman goes away to search Ram.
Third: In the movie Ramayana, Ravana can be seen wearing white thread (janev) but Ram, Lakshman and others are not seen wearing the same.
Apart from all these there are many silly mistakes shown in the movie such as Parshuram and Ram conversation is not like as it is shown in the movie. There are many other mistakes which are not mentioned in the original Valmiki Ramayana, just to glamorize the scenes.
