A weird-looking and weirdacting man is Crispin Glover (left). He's one of those guys who leaves a lasting impression no matter what he's involved in. And that's exactly what he does in Nurse Betty, which has been playing around town for about a week. Born Crispin Hellion Glover on September 20, 1964, in New York City, Glover's cards were marked in advance. His father was actor Bruce Glover (Duffy from 1974's Chinatown) and the elder Glover moved his family to LA when Crispin was a little lad. By 13, he had already appeared in a production of The Sound Of Music and soon after could be seen on TV in small roles. He attended Beverly Hills High School - and The Mirman School for gifted children - but by the time he was 17, Glover had made his big-screen debut in the woeful Private Lessons (1981). He followed that up with the equally bad My Tutor (1982) but his real breakthrough was as the gawky dad in the box-office smash Back To The Future in 1985. That role won him much acclaim and later a lawsuit when he sued Steven Spielberg for using his footage - spliced with additional material of an extra dressed up to look like him - in the film's sequel. That case was settled out of court but brought a change of laws from America's Screen Actors Guild to make sure it never happens again. But by that time - after a stunning performance in 1987's River's Edge - things had started to go a bit strange. Glover appeared on Late Night With David Letterman and seemed to try to kick the host, and then published a gruesome children's book. He then released his debut LP, The Big Problem Does Not Equal The Solution.The Solution Equals Let It Be, and left the Hollywood machine for lesser - but still memorable - roles in efforts such as Wild At Heart (he was the one with the bugs in his underpants) and 1991's The Doors (as Andy Warhol). And his work in such films has made him much sought after as the 'weird guy', leading to parts in Dead Man (1995) and Charlie's Angels (2000).
