Jesse Eisenberg has admitted he was nervous about coming face to face with Mark Zuckerberg.
The actor appeared on Saturday Night Live with Facebook founder, who he played in Oscar-nominated film The Social Network.
"I was nervous to meet him because I had spent a year and a half thinking about him," the 27-year-old actor said at the Oscars Nominees Luncheon.
"During the movie, I was watching him every day and listing to him on my iPod on the way to work and doing everything he did."
Jesse, who landed his first Best Actor Oscar nomination for his role, recently appeared alongside the Facebook CEO during the opening sequence of the American entertainment show.
"I had built up this great anticipation thinking about what it would be like to meet him and then we met under circumstances that were far more anxiety-producing which was to be on live television together," said Jesse.
"In a strange way, it was probably best to meet under those even more strange circumstances."
He also paid tribute to Mark's bravery in appearing on the show, along with acknowledging a film which, at times, does not portray him in a positive light.
"The fact that Mark has been so gracious about something that I imagine must be very uncomfortable is really wonderful," said the actor.
"The fact that he would even agree to do Saturday Night Live - to do something so silly and make fun of the situation, is so sweet and generous. It's the best possible way to handle something that could otherwise be very uncomfortable."
