I love television probably more than I should. I can never seem to remember where I put my car keys but I CAN tell you why Roger Thorpe visited Maureen Bauer's grave in the dead of night on "The Guiding Light." I find it hard to believe that other people love television more than I do but the people who mapped out the Tommyverse definitely do. What in the world is the Tommyverse? Sit down, this may take a while.
Contains Spoilers if you've never seen St. Elsewhere.
When St. Elsewhere ended in 1988 the final scene indicated that the entire run of the show had taken place inside the mind of Tommy Westphall, the autistic son of Doctor Donald Westphall. Later Drs. Turner and Erlich appeared on Homicide: Life on the Street, connecting those two universes. Detective John Munch from Homicide has made appearances on ten different television shows which I guess makes him Character Zero. This interconnected universe stretches from 1951 (with I Love Lucy) to the present and includes The Cosby Show, the Star Trek franchise, and Dr. Who. You can check it all out here but be forewarned that it's a timewaster. (Spooks geek moment: in Season 8 Episode 6 I spent more time than was really necessary trying to determine if Ryan Baisley was smoking Morleys, the brand favored by The Cigarette Smoking Man from The X-Files and Spike from Buffy the Vampire Slayer, among others. He wasn't.)
Enter Joss Whedon. "Jossed" is a Buffyverse fic writer's term for a canon plot development that scraps a fic's plot; if the fans actually named it you can safely assume that it happened a LOT. Whedon generally kept things in the Tommyverse but he did make a couple of references to The X-Files in Buffy and Angel. Did he Joss the Tommyverse? Probably not, but dude, his name is a verb. Oh, and he's writing and directing The Avengers so anything in Captain America that might have seemed final is probably fair game.
Las Vegas with James Caan is firmly in the Tommyverse and don't we all need a little more Elvis? I do.
