Ajay Devgns "Bol Bachchan" turned eight on Monday, and the actor-producer invoked Amitabh Bachchans incredible voice power to do some promotion of the superhit comedy.

"When the Bachchans speak, I listen (especially Amitji) #8YearsOfBolBachchan," Ajay wrote on Instagram, along with on-set pictures he posted.

"Bol Bachchan" was directed by Rohit Shetty and was broadly inspired by Hrishikesh Mukherjee's comedy classic "Gol Maal".

The film also starred Abhishek Bachchan and Asin, while Amitabh Bachchan essayed a special cameo in the title song.
