Jimmy arrived in Superman comics in November 1941, somewhat older, perhaps seventeen. He was a redhead, like the cliche sidekick in boys' adventure novels of the period, and his v-shaped torso suggested muscleman potential. But he was never a sidekick, like Robin to Batman, or Bucky to Captain America. Jimmy never lived with Superman, he never learned Superman's secret identity, he only participated in the adventures by accident. Was he homoromantic partner, or merely a coworker and pal?
In Jimmy Olsen's comic book series, which began in 1954, it doesn't take a lot to find the romantic subtext beneath the boy pal text. But in the tv and movie versions of the mythos, things are a little different.
Jack Larson is gay, and even states that he was out on the set during the period; maybe that explains why he kept Jimmy carefully free of any romantic feelings for Superman.
Dean Cain and Terri Hatcher as the famous couple (yes, now a couple), with the standard antipathy turning into romance ("He's so...arrogant!").
Jimmy was played by Justin Whalin, a former child star (the child of lesbian parents in a 1993 School Break special). Given the hetero-romantic story arc, it would seem that Jimmy would be a third wheel, but he actually has an unrequited crush on the hunky Clark. And there are a few Jimmy-rescues.
Smallville (2001-2011) was about Superboy, the teenage Clark Kent, so Jimmy (Aaron Ashmore, left, with an unidentified hunk) was not introduced until Season Six, when Clark arrived in Metropolis.
Jimmy had at least two girlfriends during his three years on the program, and expressed any romantic interest in Clark or Superman.
Clark Kent (Tom Welling) did have a homoerotic bond with a young Lex Luthor (Michael Rosenbaum), but not with Jimmy.
Not a very good record. Where there is a gay subtext at all, it is between Clark Kent and someone else. Why has one of the most substantial and overt homoromances in all of comics failed to make it on the small screen?
