Jeff Bridges "didn't want to offend" method actor Jared Leto on the set of Tron: Ares.

The 75-year-old actor explained how his co-star wanted to be called by his character's name Ares while they were on set but he struggled to do so as he wanted to build a relationship with Jared, 53.

According to The Hollywood Reporter, Jeff said at San Diego Comic-Con: "He's one of those guys. Everyone has different methods and modes man.

"I didn't want to offend him as a thespo. But I thought, 'I wanted to have a certain intimacy with you. I know your name is Ares. Can I just call you Air?' He said, 'Yeah man! You can call me whatever you want!' We had a great time."

And, Jared shared how excited he was to work with Jeff, even calling cut in the middle of a scene because he could not stop smiling.

He said: "I just blurted out, 'cut!' Everyone was surprised, because I don't often do that. The first AD comes over and said, 'Is everything OK? What's wrong?' And I said, 'You know, I just can't stop smiling, because I'm working with my guy.'"

The film - which follows on from the events of 2010's 'Tron: Legacy' - follows the computer software Ares (Leto) which is sent from the digital world into the real world to introduce artificial intelligence to humans.

Bridges reprises his role as video game designer Kevin Flynn who was first introduced in the 1982 original movie.

Writer/ director Steven Lisberger said: "My feeling about Tron is the most important thing is we kick this technology around artistically before it kicks us around."
