Gulumaal- The Escape seems to be a copy of the Hindi movie Bluffmaster. Gulumaal story tells about two yuongsters Jerry (Jayasurya) and Ravi Varma (Kunchacko Boban) who lives by swindling money.
The Hindi movie Bluffmaster is also a similar story where Abhishek Bachchan plays the role of a swindler. The two movies have the similar concept. Yash Raj's Bunty Aur Bubli also had a similar story in its backdrop. Gulumaal is much more similar to Bunty aur Babli it seems. Whatever it be, the movie is having a good response
