Toni Collette to join Maya Rudolph in new comedy

Toni Collette will join John Krasinski and Maya Rudolph in an upcoming relationship comedy from "American Beauty" director Sam Mendes.

Krasinski ("Leatherheads") and Rudolph ("Saturday Night Live") star as a couple who canvas the country to find the best place to raise their unborn child.

Collette ("Little Miss Sunshine") will play a college professor and close family friend convinced that the kid will end up dysfunctional no matter where it's raised. Cheryl Hines ("Curb Your Enthusiasm") also will appear.

Dave Eggers wrote the script for the untitled Focus Features project with his wife, novelist Vendela Vida. Filming begins this month in Connecticut.
