The movie starts with a lie, which results in comedy of errors. Abbas (Abhishek Bachchan) lies to the most powerful man of Ranakpur, Prithviraj (Ajay Devgn).
Abbas was suffering from financial problems which lead him to his uncle Shastri's (Asrani) house in Ranakpur, to get a job to take care of himself and his sister Sania (Asin). Abbas accidentally falls to a situation which makes his friend Ravi (Krushna) lie about Abbas name. He then gets a job as a supervisor with the lie hater Prithviraj. Then starts series of lies in front of his boss. He also falls in love with Prithviraj's sister (Prachi Desai).
Ajay is super-efficient and his comic timing is very strong in the movie. Ajay's desirability to speak in English language brings strong humor. Abhishek also acts well in the movie, with his superb performance as Abbas as Gay. His dancing act at the interval point is incredible.
Asin also does well with her limited screen time. Prachi Desai gets good opportunity to showcase her talent. Krushna Abhishek is supremely talented and has strong sense of humor in this movie. Archana Puransingh is, as always, fabulous. Asrani once again does complete justice to his role.
The movie has some amazing action scenes as Rohit Shetty showcases in most of his movies, with vehicles flying in the air most of the time.
On the whole, Bol Bachchan is an entertainer with comedy and action. The ending of the movie is very much stretched, making difficult for the audience to sit on their seats. TRP gives BOL Bachchan 2.9+ stars out of 5!
