The Phantom of Hollywood

The Phantom of Hollywood is a 1974 TV movie starring Jack Cassidy, Skye Aubrey, Peter Lawford, Jackie Coogan, Broderick Crawford, Peter Haskell, John Ireland and Corinne Calvet. It is notable for being one of the last films shot on the Metro Goldwyn Mayer back lot, which was being demolished at the time of filming.citation needed

Murders taking place on the back lot of Worldwide Studios turn out to be the work of a disfigured actor who has been living there for years and will stop at nothing to cease the sale of the back lot to developers. The film seems to place a lot of emphasis on the chalk outline and one character is even heard to quip, Were going to be running out of chalk, while standing over a murder scene in a dry pool on the set.
