The self-styled Latin from Manhattan Cesar Romero was born in 1907 in New York City to a well-off family. His father, an Italian immigrant, owned a company that imported and exported sugar refining hardware and his mother was a concert singer from Cuba. While they enjoyed financial success early in Romero's life, damage to the business in the late 1920's led Romero to support his family with revenue from Hollywood.

Romero first attempted a career at banking, but Lisbeth Higgins met him by chance and started him down a path of professional dancing. His success on the stage led Metro-Goldwyn-Mayer Studios to pick him up for a role in "The Thin Man" in 1934. This led to him starring in "the Return of the Cisco Kid" and being taken on by Twentieth Century-Fox in 1937.

In 1942, Romero enlisted in the U.S. Coast Guard and served aboard the USS Cavalier. Romero made a concerted effort to operate as part of the regular crew and didn't ask for any special considerations. He won the respect of his shipmates who considered him one of the best winch operators they'd ever worked with. Romero's duties including shifting 18,000 lb barges from the transport ship into the water during assaults, operating as a powderman on the forward gun, and others. During downtime, Romero entertained the crew with a variety show.

After the war, Romero played in numerous supporting roles and was often cast in the "Latin lover" archetype. He acted in many notable films including "Ocean's 11," "Captain from Castile," and Week-End in Havana. He also appeared frequently on television in comedies, dramas, and most notably as the Joker on ABC's "Batman."
