Saif, Jimmy Shergill new gym buddies
Saif and Jimmy have earlier worked together in films like "Eklavya" and "Hum Tum" but they never got a chance to connect as co-actors.
But thanks to the long shooting schedules of "Bullett Raja" in Lucknow and Kolkata, the actors got to bond with each other especially over their passion for the gym.
A source close to the team said: "Saif and Jimmy both are very passionate about working out. The team was asked to give them a break in the evening so that they could go to the gym.
"Apart from discussing their daily regime in the gym, they were seen discussing their love for Lucknowi food, films, gadgets and much more."
Action-drama film "Bullett Raja" will release Nov 29.
"In terms of stunt spectacle and action, we have gone way beyond the other 'Krrish' films," Hrithik told film critic Anupama Chopra on her TV show "Star Verdict".
The actor plays the lead in the third instalment of the franchise that began with 2003 hit sci-fi movie "Koi... Mil Gaya".
"Krrish 3" releases Nov 1.
