One of the most popular sitcoms of all time, "FRIENDS," will be having a reunion episode but it looks like the cast will not be complete due to a conflict in schedule.

There will be a reunion episode of "FRIENDS" to honor the legendary comedy director James Burrows. Sadly, one of the cast members of the show might not be present on the day of the shoot.

Actor Matthew Perry will not be able to go to the shoot because he will be in London at that time for a rehearsal of a play entitled, "The End of Longing."

According to USA Today, Lisa Kasteler, Perry's spokeswoman, said that the network is well aware of the actor's schedule even before the announcement was made.

NBC's Entertainment chairman Robert Greenblatt said that he'll do everything in his power to have all of the cast members in the said reunion episode.

"We'd like to get all six of them in room at the same time, but I'm not sure we can logistically pull it off," he said.

It was reported that the shoot will happen on January 24 while the episode itself will be aired on February 21 on NBC. They just might have to shoot the 46-year-old Perry from outside the studios. Viewers could only hope that the finished product would still feel like a reunion despite the problem that they are facing right now. The reunion episode will still happen, although the characters will not be complete in the same room as they shoot it.
