•Grind

Strictly for those who live to skateboard. This dopey teen comedy follows four board-toting youths as they take to the road in a van—the heck with college—seeking sponsors to fulfill their dream of turning pro. While the skateboarding sequences feature daring stunt work, it's obvious that we're seeing doubles doing the triple turns. The cast features Mike Vogel, Adam Brody, Joey Kern and, in an over-the-top turn as an obnoxious goofball, Vince Vieluf. (PG-13)

•The Secret Lives of Dentists Campbell Scott is top-notch yet again, as a dentist who fears his wife (Hope Davis), also a dentist, may be cuckolding him. (R)
