The iconic hillside sign overlooking Southern California's film-and-television hub was defaced overnight in honor of marijuana.

Residents awoke on Sunday to find "Hollyweed" staring down at them in four-story, white letters from Los Angeles' Mount Lee, where a version of the picture-ready "Hollywood" sign was first erected in 1923.

City surveillance cameras captured footage of someone dressed in black at 3 am whom police believe was behind the conversion, Sergeant Robert Payan of the Los Angeles Police Department said.
