So how are crossovers possible when sometimes the rules of one television show's universe completely contradict the rules of another? I think it's the way that real-life people can show up in fictional universes, such as with presidents.
Presidents do fictional things all the time, and I'm not talking politics. I mean, President Bush can meet George Lopez when clearly he's done no such thing in real life in the way it was depicted. There must be some kind of class of
ur-character, or,
uber-character, that by himself in real in his own universe but also has fictional versions. Tommy Westphall could be dreaming about someone who already exists, for example. Probably the easiest explanation, and the one that makes the most sense. I think that was a point brought up in the thing I showed you.
For those unsatisfied with the way the
Mission: Impossible film treated Jim Phelps, think of it as: the events of the show were canonical to the film, but the events of the film were not necessarily canonical to the show (where does the 1988
Mission come into all of this? It's kind of a remake, and kind of a sequel- I guess this attitude serves to make
that much less confusing as well.)
