Tina Fey has been keeping pretty busy in this post-'30 Rock' world. Her latest job teams her up with Jason Bateman for the sibling comedy 'This Is Where I Leave You.'

THR reports that Tina Fey has joined the cast of 'This Is Where I Leave You,' the latest film from director Shawn Levy ('Night at the Museum'). The film follows a man (Bateman) who tries to get his four siblings together following his father's death by asking them to stay in their parents' home for an entire week straight. Fey will play his older sister, a married woman who returns home to discover her first boyfriend has brain damage.

The site also reports that Bateman has been reading with various actresses for the part of his romantic interest in the dysfunctional family comedy, including Mary Elizabeth Winstead, Ari Graynor, Zoe Saldana, and Isla Fisher. Kathryn Hahn will also probably join the cast as Bateman's sister-in-law.

Bateman recently starred in 'Identity Thief' opposite Melissa McCarthy, and can be seen reprising his role as Michael Bluth when 'Arrested Development' releases a new season on Netflix in May.

Fey will begin work on 'This Is Where I Leave You' once she completes 'The Muppets... Again!' and she can be seen this month alongside Paul Rudd in 'Admission.'
