Will Arnett is set to play Christina Applegate's husband in a new NBC comedy pilot spearheaded by "Saturday Night Live" creator Lorne Michaels and writer Emily Spivey.

The Canadian-born 40-year-old actor has for the past three years had a recurring role on the sitcom "30 Rock" and played "George "Gob" Bluth II" on the cult comedy series "Arrested Development" between 2003 and 2006. He also starred on the short-lived show "Running Wilde" last year.

In the new single-camera pilot, Applegate, 39, portrays an acerbic working mother. Arnett's spokesperson confirmed a report by The Hollywood Reporter that said Arnett will play her stay-at-home husband.

The parenting-themed project also features the opinionated parents of Applegate's character, the Hollywood Reporter said. No announcement has yet been made as to who will portray them.

If the project is picked up and more episodes are ordered, it could mark Applegate's return to television, two years after her old show "Samantha Who?" was canceled. The actress is also one of the producers, her spokesperson had told OnTheRedCarpet.com. No filming date has yet been announced.

Meanwhile, Arnett is also set to guest-star on the season seven finale of "The Office" on May 19, which will be main actor Steve Carell's last show. Carell had played the egotistical boss Michael Scott since the show premiered in 2005 and had announced his plans for departure last year.

Ricky Gervais, who played a similar role on the previous UK version of "The Office" and co-created both shows, will also appear on the finale. He said on his blog in February: "Had a little meeting with NBC about various things and recommended Will Arnett for a regular in 'The Office.' Thoughts? I think he's amazing."

NBC has not announced who will replace Carell. Arnett has not commented on Gervais' remarks.

"Saturday Night Live" cast member-turned film star Will Ferrell is set to play an "inappropriate branch manager" on four episodes of "The Office," starting on April 14.
