The much-loved 1994 American sitcom Friends did feature some cameo in its long run of 236 episodes. One is the Oscar-winning actor Julia Roberts and here`s how Matthew Perry, who played Chandler Bing, went the extra mile to convince her to star in the show. Ahead of its rebooting, in an interview with The Hollywood Reporter, the producers, writers and staff of the hit show revealed how Perry went above and beyond to impress and land the Oscar winner star in the show.

"Matthew asked her to be on the show and she wrote back to him, `Write me a paper on quantum physics and I`ll do it.` My understanding is that Matthew went away and wrote a paper and faxed it to her the next day," the executive producer Kevin Bright told.
