OyeMamu, which is releasing on August 6, launched its first poster on Tuesday. The movie revolves around a warring mama and bhanja. Ruslaan Mumtaz is charming and funny as mamu, while Tanay is cute as his naughty bhanja. Kulraj Randhawa is essaying the role of a cop. Bollywood’s favourite baddie Gulshan Grover is playing the antagonist and we are quite excited to see him entertain the audience with his comic timing in OyeMamu! Add to this comedy veterans Asrani, Tiku Talsania, Mohan Kapoor and Brijendra Kala for some solid laughs.
