I would say that the most recent Star Wars movie and the Lost World are definitely on the flameout list, but I don't know what else makes it.

Thinking about our upcoming all-pirate Super Bowl, I starting thinking about the last time a major sports championship was played between two teams with the same mascot, loosely speaking. I got hung up on the Dallas Cowboys vs. the Buffalo Bills -- was Buffalo Bill a Cowboy? Going back a little farther, in Super Bowl XI the Raiders defeated the Minnesota Vikings, but I think a lot of people of Nordic origin might object to the classification of Vikings as "raiders." We're still awaiting Redskins-Chiefs and Giants-Titans matchups, as well as my favorite: Steelers-Packers (the Battle of Blue Collar Rust Belt Workers).

As for other sports, I don't know what all the mascots used to be in the olden days of baseball and basketball, but I found these matchups: Cleveland Indians vs. Atlanta/Boston Braves in 1995 and 1948; Cincinnati Reds vs. Boston Red Sox in 1975; and, to stretch things a bit, Detroit Tigers vs. Chicago Cubs in '45, '35, and '08. We're still awaiting Blue Jays-Cardinals, Orioles-Cardinals, and Devil Rays-Marlins World Series matchups. (Which of those do you think will be the last to happen?)

In basketball: The San Antonio Spurs played the New York Knickerbockers in the all-legwear finals of 1999, and the Seattle Supersonics played the Washington Bullets in '79. We're eagerly awaiting the Philadelphia 76ers vs. the Sacramento Kings, the Cleveland Cavaliers vs. the Dallas Mavericks (Cavs v. Mavs!), and perhaps the New Jersey Nets vs. the L.A. Clippers.
