Rumors of a Friends reunion have been spreading for years and actress Emily Blunt was the latest to unintentionally spread one. It all started on the set of Girl on a Train, Blunt's recent psychological murder thriller. In the film, Lisa Kudrow plays her friend and they meet at Central Station. Blunt's character's name is Rachel and Kudrow's character's name is Monica. There were about 300 extras on site for the scene and production was heard over the loud speaker saying, "We're going to roll on Rachel," and "We're going to do a close-up on Monica." Fans of the 90s comedy started freaking out, asking "Is this Friends?" The rumors were quickly squashed and Kudrow's character's name was promptly changed to Martha to avoid any further confusion!
