Harvey Weinstein is back! Or, as a guy loading buses put it to me at the Eccles Theater, “It’s getting spendy out there.” Said bus-loading guy told me that the Weinstein Co. splashed out $7 million, plus a $15 million P& A commitment (I can’t find the source for the latter figure, but the guy was reading it off his iPhone; Variety has reported the $7 million figure) for the sort-of mainstream comedy about a gentle Cosmo Kramer type who exasperates his sisters with his stubborn honesty and naivety. Star Paul Rudd has headlined a couple of studio comedies lately — “Role Models” and “I Love You, Man” — and the Weinsteins must be hoping the pic will do roughly as well as those two. It seems like a gamble to me. The movie’s funny and sunny but it also feels kind of small; it’s about at the level of a top-quality sitcom. It has a somewhat limp ending and the setup gets slightly stale in the last 30 minutes. I’d give it three stars, probably. Now I’m off to see “Cedar Rapids.”
