Toni Collette has joined the cast of the still-untitled Sam Mendes relationship film -- you know, the one starring John Krasinski and Maya Rudolph, and being penned by Dave Eggers and Vendela Vida.

According to The Hollywood Reporter, Collette will be playing a college professor and close friend of the young couple -- two folks who are scouring the country for a place to settle and raise their child, and Collette's character feels that it'll be dysfunctional no matter where they end up. Smart lady!

The movie pairs Collette up again with Big Beach producers Marc Turtletaub and Peter Saraf, who produced Little Miss Sunshine. Focus is hoping to capture a bit of that magic, since they gave up their claim on that enormous indie hit.
