Jennifer Lawrence once told Jimmy Fallon (on Late Night) that she knows "every word" to Dumb and Dumber, so it comes as no surprise that she's joined the cast of the upcoming sequel. Apparently she filmed a quick cameo for Dumb and Dumber To wherein she'll play a younger version of Kathleen Turner's still unspecified character, made easier by the filming location's short distance from Mockingjay's.

Dumb and Dumber To, set for release next year, will follow Harry and Lloyd on a road trip to find Harry's long-lost daughter.
