And… I don't know why I didn't think of this before, but why not Amy Poehler in the Rick Moranis role? If anyone could pull it off, she could!

Though, I think Aubrey Plaza and Emma Stone would be fabulous, too…

I'm seeing Aisha Tyler, Margaret Cho, Ellen Page, Melissa McCarthy, Kristen Schaal in the Annie Potts role, and Jon Hamm in the Sigourney Weaver role.

Sadly, he is not.
