War of the Colossal Beast (1958)
Glenn Manning, "The Amazing Colosasal Man," believed dead after falling from the Hoover Dam, reemerges in rural Mexico, brain damaged, disfigured, and very hungry.
Eventually he makes his way to Los Angeles (like most monsters tend to do) and finds out that not only the dating scene for giant men very tough, but people don't seem to understand his obsessive compulsive need to destroy things. Things are much different then they were in the 1950s.
