If and when Robert DeNiro‘s performance as Jennifer Lawrence‘s dad in Joy results in Best Supporting Actor heat (and I know nothing about that), Dan Mazer‘s Dirty Grandpa (Lionsgate, 1.22.16) might get in the way. Maybe, possibly. DeNiro’s grandpa to Zac Efron, verbatim: “The greatest gift a grandson can give his grandfather is a hot college girl who wants to have unprotected sex with him before he dies.”
