matthew perry go on 1 nbc 'Go On': Matthew Perry returns to NBC    how does his post 'Friends' career stack up?Matthew Perry begins his third starring role in a TV series since the end of “Friends” Wednesday (Aug. 8) when his new NBC comedy, “Go On,” gets a commercial-free preview following the Olympics broadcast.

He’s probably hoping it goes better than the other two: Both “Studio 60 on the Sunset Strip” and “Mr. Sunshine” were canceled after just one season. Perry has done acclaimed guest work in dramas — he was nominated for a guest-acting Emmy on “The West Wing” in the final season of “Friends,” and he had a well-received turn on “The Good Wife” last season — but his post-“Friends” lead roles haven’t panned out.

In that regard, he’s not unlike his fellow “Friends” stars, all of whom have had some serious ups and downs since their career-defining roles on the NBC sitcom.

Jennifer Aniston has easily had the highest profile of the six stars, but her movie career since 2004 has had at least as many flops as hits. Courteney Cox followed up the short-lived “Dirt” with the more successful “Cougar Town,” and Lisa Kudrow has done work both in front of (“The Comeback,” “Web Therapy”) and behind (“Who Do You Think You Are?”) the camera.

The other male “Friends” have had their ups and downs too: Matt LeBlanc‘s turn in Showtime’s “Episodes” is helping people forget “Joey.” David Schwimmer is part of a very successful animated movie franchise (he voices Melman the giraffe in the “Madagascar” movies), and has concentrated as much on directing and producing as he has acting in the past eight years.

We’ve collected the post-“Friends” highs and lows for each of the six stars in this photo gallery, but we want to know what you think: Which “Friends” star has had the best career since the show ended in 2004? Vote in the poll below and talk it out in the comments.
