The quirky bunch on 'Scrubs' are ready to make their fans laugh once again when the new season of the medical comedy premieres on Tuesday, moved from NBC over to ABC.

After the show's seventh season finale, there were many questions as to whether "Scrubs" would even have an eighth season, and the mid-season ABC move is not striking a lot of fans as the best idea. However, most agree it is great to see the return of a half-hour this charmingly performed and superbly written, particularly when there is such a primetime network comedy shortage.

"We return tonally to the beginning and walk that line between comedy and drama again," creator and executive producer Bill Lawrence said.

Joining the cast for this 18-episode mini-season is Courtney Cox as the new, crazy (somewhat waxy-looking) Chief of Medicine, who is replacing Dr. Bob Kelso, played by Ken Jenkins. Cox and Lawrence are already working on a new show called "Cougar Town."

Speaking about the new addition to the cast, actor Zach Braff, who plays Dr. John 'J.D.' Dorian on the show, said the crew had no idea who would play the character but when they were told it would be the "Friends" star, everyone got very excited.

"There are a lot of actors who do movies, but (if you get them) they may not make John Q. Public to tune in to 'Scrubs.' With Courtney, we have the best of both worlds," Braff said.

The season will also feature a bunch of new interns (including Betsy Beutler, Eliza Coupe and Sonal Shah). Aside from Braff, who already hinted he's ready to move on to other projects, Donald Faison (Dr. Christopher Turk), John C. McGinley (Dr. Perry Cox), Judy Reyes (Carla Espinosa) and Sarah Chalke (Dr. Elliot Reid) were also back on the show, which already wrapped up shooting.

"JD's still is struggling to maintain a female relationship," Braff of his character in a recent interview. Last season, we witnessed J.D. as he became a father for the first time.

"He's got a kid now. That's making him grow up, so even though he's not with Elizabeth Banks (Kim), he's going to eventually want to settle down. Getting older and having a kid makes him want to experience the next phase of his life."

Bill Lawrence recently said that for the season finale he wanted to give loyal fans what they want as J.D. says goodbye to Sacred Heart Hospital. "Scrubs" might be picked for more episodes but in a different form after this season. 

"For the show to end and for anybody to give a crap about the characters, it has to have more dramatic overtones. If it works, the old fans will be happy, and if it doesn’t, it’s the last year anyway, so they won’t be able to hold a grudge that long," Lawrence explained.

The new 18-episode season, including a one-hour finale, will answer important questions for the show's diehard fans. (What is janitor's real name? or are on-off lovers Elliot and J.D. going to end up together?)

As far as Braff's next move is concerned, the actor said he doesn't plan to act in another TV show. His attentions are more towards replicating his "Garden State" cinematic experience.

"I'd like to direct my second film. I've got a whole bunch of movies I'd like to make and others' movies that I'd like to act in. It's probably time for a new chapter," said Braff who has been with the show for eight years.
