[4] His first Hollywood job was as a stand-in for Elvis Presley in the 1956 movie Love Me Tender.
[citation needed] In 1971, Webb offered Lopez the role that would bring him into the homes of millions of Americans weekly, that of Firefighter Marco Lopez in Webb and Robert Cinader's television series, Emergency!
co-star, Los Angeles County Fire Department engineer and actor Mike Stoker, Lopez used his real name as his character name (which led to confusion that he was an actual firefighter with the LACoFD - he had never worked with the LACoFD at any time).
He also appeared opposite Catherine Zeta-Jones and Julia Roberts in the movie America's Sweethearts, where he had an uncredited role as a photographer.
Lopez was also one of the original "extra" crewman on Voyage to the Bottom of the Sea, a show he lent his visage (though seldom his voice) to from 1964 to 1968.
