During the summer of 1948 actor Robert Mitchum was busted for marijuana possession and sentenced to a brief stint in jail. He served part of his time doing hard labor making cinderblocks at Sheriff’s Honor Farm, north of Los Angeles in the town of Castaic, and in the above photo is being transferred to L.A. County Jail to finish his sentence in a cell. That was today in 1949.
Note: Wikipedia and other sources seemingly get Mitchum’s jail chronology backwards. They say Mitchum served his county time first, which means he would have been slaving under a hot sun in Castaic on this day. But he wasn’t—at least, not according to the photo’s label, which is contemporaneous with the shot.
