Tina Fey gets to turn the Broadway musical based on her generation-defining teen comedy onto the screen in a January release.

This looks repetitive — same basic plot, no Lindsay Lohan/Rachel McAdams, et al. — but fun.

Jon Hamm, Jenna Fischeer, Busy Philips and and Tim Meadows join Tina F among the adults in this Friday release.

The teens — mean or otherwise — include Reneé Rapp, Avantika, Bebe Wood and Angourie Rice.
