This week’s episode of Eureka was fun. They did the old body swapping thing, with the swapping happening randomly and at hilariously inconvenient moments.

This trope* has been around a long time. The earliest I remember is the famous Captain Kirk/Dr. Janice Lester switch in Star Trek: TOS but I’m sure that is not the earliest example. (*Beware of that link. If you’re not careful you could be trapped for hours upon hours.)

The thing I find interesting about body swapping or snatching is watching how well (or how poorly) the actors portray someone else. My favorite was in Fringe earlier this season (or was it last season) when Olivia (Anna Torv) was invaded by William Bell (Leonard Nimoy) It was downright uncanny! Of course it’s easier when the swap or snatch involves characters with really distinctive speech mannerisms but Torv is brilliant at this sort of thing. She also gets to play two subtly different versions of her character.

So anyway, let’s discuss this. Do you have any favorite examples of body swapping or snatching? Or do you just find the whole thing silly, lame, tiresome and done way too often?
