The Wedding Party (1969) review

Friends and relatives gather at an estate on Shelter Island, New York to be a part of the wedding ceremony for Charlie (Charles Pfluger) and Josephine (Jill Clayburgh, in her film debut) and several incidents occur: a lightning storm causes the power to briefly go out, the nanny (Sue Ann Gilfillan) keeps interrupting Charlie and Josephine "fooling around" and Charlie's buddies Alistair (William Finley) and Cecil (Robert De Niro) offer him "advice" but later on have to stop him from being a Runaway Groom.  This very early De Palma outing, which he co-wrote and co-directed with his Sarah Lawrence professor Leach and fellow student Munroe, is crude and amateurish (there are too many sped-up and slowed-down sections), although it does have an undeniably scrappy energy to it and there are some engaging moments, like an intoxicated Charlie trying to seduce chirpy-voiced Celeste (Judy Thomas) ... and then stopping himself.  The movie shows the events from a male point-of-view, so I'm kind of curious if the Josephine character was having second thoughts as well....
