As: Thomas Magnum (duh)
The original run of Magnum, P.I. of course overlapped with that of The Dukes of Hazzard. But in an alternate universe, Tom Wopat was available for both series. As the titular character in Magnum, P.I., he would’ve given the character the same laid-back, easygoing sensibility that Tom Selleck did, but with more made-for-Hawaii good looks.
Wopat as Magnum would also have eliminated the scheduling conflict that caused Selleck to turn down the role of Indiana Jones in Raiders of the Lost Ark. What a different world American cinema would’ve been had Tom Selleck become as massive a movie star as Harrison Ford did following that film’s success.
For one, it’s doubtful that Wopat would’ve worn a ‘stache like Selleck’s. That seems to have been brought to the character solely by Selleck—Magnum wasn’t necessarily written as having a mustache.
Second, Magnum’s Detroit Tigers baseball cap would likely have been replaced with a Milwaukee Brewers one. Selleck, having been raised in Detroit, also added that touch himself. (If memory serves, the pilot script had the character in a New York Yankees hat.) Wopat, born in Lodi, Wisconsin, and a graduate of the University of Wisconsin-Madison, is more than likely a Brewers fan.
Also, while Tom Selleck’s Thomas Magnum wore Aloha shirts almost exclusively, Tom Wopat’s Thomas Magnum would probably have appeared shirtless much more often. The weather in Hawaii is certainly conducive to this, as are Wopat’s dashing good looks. The show got good to great ratings as it was; with every episode featuring scenes with a shirtless Tom Wopat, ratings would’ve been through the roof!
Additionally, while Selleck certainly had his share of rough-and-tumble exploits as Magnum, Wopat’s stunt work in Dukes suggests the even more action-oriented Magnum, P.I. that could’ve been. I know I saw a few karate moves in Luke Duke’s fightin’ repertoire—imagine Thomas Magnum spin kicking a guy right into the ocean!
Other than those few tweaks, the show could’ve been largely the same. Except ten times better, because Wopat.
