About half-a-million people are expected in Tinseltown on Sunday for the 75th Hollywood Christmas Parade, featuring the usual array of celebrities, marching bands and, of course, Santa Claus.

Actor-comedian George Lopez will be the grand marshal of the parade, which will begin at Hollywood Boulevard and Orange Drive and follow a 2 1/2- mile route east to Vine Street, then south to Sunset Boulevard and back west to Orange, ending at Hollywood High School.

Brooke Hogan and Michael Bolton are among the singers scheduled to perform during the parade — which kicks-off at 5 pm. and is expected to last about two hours. At least 16 floats will be featured during the procession.

Regis Philbin will be an honorary grand marshal. Other celebrities scheduled to take part include Joey Lawrence, Casper Van Dien, David Boreanaz, Stephen Collins, Catherine Hicks, Edward James Olmos, Dick Van Patten, Leeza Gibbons and Marlee Matlin. Mayor Antonio Villaraigosa, last year’s grand marshal, will also be on hand.
