LIP SERVICE A new documentary on the Oklahoma art-rock band the Flaming Lips, “Fearless Freaks,” begins its run at the Pioneer Theater. Director Bradley Beesley, who met lead singer Wayne Coyne in art school 15 years ago, has been following the band since the beginning. He has documented the band’s early days as it refined its distinct sound, the members’ personal struggles, and the theatrical live shows that often incorporate large animal suits and confetti. In the mood for more rock-on-film? The theater also offers a screening of the Ramones documentary “End of the Century” (tomorrow, 7 p.m.). “Fearless Freaks”: Tonight through Tuesday, 9 p.m., Two Boots Pioneer Theater, 155 E. 3rd St., between avenues A and B, 212-591-0434, $9 general, $6.50 members.

FAMILY TROUBLE Film critic and historian Elliott Stein participates in a discussion after a screening of Curtis Harrington’s “The Killing Kind” (1973).
