From USC Athlete to a Successful Male Model

Before the iconic mustache became synonymous with Thomas Magnum, young Tom Selleck was a ubiquitous face in American advertising, supporting himself through a highly successful modeling and commercial career throughout the late 1960s and 1970s.

His earliest television appearances weren't dramatic roles, but rather game show spots. Selleck appeared on *The Dating Game* not once, but twice, in 1965 and again in 1967, showcasing his handsome, clean-cut look.

The modeling work was steady and lucrative, with Selleck appearing in countless print advertisements and TV commercials for major brands. He sold everything from deodorant and cigarettes to soft drinks.

One of his most famous early gigs was a commercial for Pepsi-Cola. His work as a rugged, masculine figure often put him in 'cowboy' roles in ads, which led to a widespread association with the Marlboro Man image, though he was never the official face of the campaign.

This decade of commercial work honed his on-camera skills and gave him the financial stability to pursue larger acting roles, even as they remained elusive. Many of his peers, like Ted Danson, also started their careers as print ad models before their acting breakthroughs.

The Crucial Roles Before the Hawaiian Shirt

The path to *Magnum P.I.* was paved with bit parts, uncredited roles, and a few key recurring characters that proved his acting chops were more than just good looks. This period, from 1970 to 1980, was his decade of grinding persistence.

1. The Bizarre Film Debut: Young Stallion 4

Selleck’s first credited film role was in the 1970 adaptation of Gore Vidal’s controversial novel, *Myra Breckinridge*. He was listed in the credits as "Young Stallion 4" in the bizarre, star-studded film that featured Mae West. It was a small, almost unnoticeable part, but it officially marked his entry into feature films.

2. Early Thriller Appearances

Throughout the 1970s, Selleck took on small roles in a variety of films and TV movies. A notable appearance was in the 1978 medical thriller *Coma*, directed by Michael Crichton and starring Michael Douglas. He also appeared in *The Gypsy Warriors* in 1978. These roles were stepping stones, allowing him to work alongside established Hollywood names.

3. The Prequel to Magnum: Lance White

Perhaps the most significant role before *Magnum P.I.* was his recurring guest spot as the dashing private investigator Lance White on *The Rockford Files*. Beginning with the episode "White on White and Nearly Perfect" on October 20, 1978, Selleck played the polar opposite of James Garner’s Jim Rockford.

Lance White was the "goody-two-shoes" private investigator: handsome, impeccably dressed, wildly successful, and loved by the police, driving the down-on-his-luck Rockford crazy. This role was a clear precursor to his breakout, essentially auditioning him for the part of a charming, successful P.I. on a major network show.

4. The Indiana Jones Conundrum

The ultimate turning point and near-miss of young Tom Selleck's career came in 1980. He was famously offered the role of Indiana Jones in Steven Spielberg and George Lucas's film, *Raiders of the Lost Ark*.

Selleck was enthusiastic, but fate intervened. He was already under contract with CBS for the pilot of *Magnum P.I.*, and the network refused to release him for the film. Harrison Ford ultimately took the role, launching a blockbuster franchise. Although Selleck missed out on the film, *Magnum P.I.* was greenlit, and the rest is television history. The series, which premiered in 1980, finally gave him the stardom he had pursued for over a decade.

Young Tom Selleck’s decade of struggle, from his days as a USC basketball player to his ubiquity as a male model in commercials, illustrates the long, arduous road to overnight success in Hollywood. The persistence he showed through bit parts in films like *Myra Breckinridge* and the crucial, pre-breakthrough role of Lance White in *The Rockford Files* ultimately prepared him for the global phenomenon that was *Magnum, P.I.* His early career is a testament to the fact that even the most iconic stars must pay their dues.
