Born Louis Morelli, he was a brief contract player for 20th
Century-Fox in the early 1960s. Before being discovered he was a used
car salesman. Fox hoped to capitalize on his
Rock Hudson-type sex appeal
and cast him in two big movies opposite two of its stars,
Eu, Ela e o Problema (1961) with
Susan Hayward
and
James Mason and
Aconteceu em Atenas (1962) starring
Jayne Mansfield. Mansfield and Colton had a
brief affair during their filming time together. Fox's plans to
make him a heartthrob never panned out and he left the industry.
