Portrait of an American psycho as a new dad: Seann William Scott (one of the raunchy high schoolers in the gross-out classic American Pie) stars in the pitch-black comedy Bloodline, a family man who happens to be a serial killer. Dividing his time between rocking his son to sleep and murdering strangers proves stressful, however, and his work-life balance begins to shift out of whack. Henry Jacobson directs this Blumhouse presentation. Los Feliz Theater, 1822 N. Vermont Ave., Los Feliz, Fri., Sept. 20, various showtimes; $6.50-$9.50. (323) 664-2169, vintagecinemas.com.
