In the famous episode of "Friends", "The One After the Superbowl", - starring Brooke Shields, Chris Isaak and Jean Claude van Damme - Julia Robert could have been absent, if it were not for her persistent, strange, e Matthew Perry-t.

In an interview with the Hollywood Reporter, the producers revealed that it was Perry, with the help of staff, who convinced Julia Robert.

"Matthew asked her to be on the show. She wrote, 'Write me a letter about quantum physics and I will come'. He left, wrote a letter and faxed it to him the next day, "said executive producer Kevin Bright.

Alexa Junge, screenwriter, said the actors may have met before the episode, as there was an interest on the part of Julia Robert.

"There was flirting with fax communication. She asked him about things like, 'Why should I go out with you?'. We helped all the screenwriters explain why. He could have done very well without us, but there was no question that we were on his side.

In fact, communication worked. Robert and Perry also had a brief romance in 1996, the same year the episode aired, which they kept very private.
