In my area, this movie is available to rent as "Invasion!" It also has a holographic box, and the picture of Campbell Scott looks eerily like Martin Sheen. Don't let any of these factors deter you from renting the movie. It is a little known gem. Even video clerks don't know about it, they'll look on you with scorn when you bring it to the counter. But it's worth their scorn, trust me.
This movie parodies the original Invasion of the Body Snatchers, as well as other 50's sci fi classics. But it doesn't just do a basic plot parody with dumb jokes plastered over it, a la Airplane or other Hollywood broad parodies. Top of the Foodchain gets into little details, like making fun of how all men in 50's sci fi seem to have traditionally female names (see cast list) or the bizarre, ham handed way that those movies dole out religious platitudes and hypocritically pro- and anti-science ideology.
Campbell Scott is, as usual, dead on in his mimicry -- this time of 50's leading man mannerisms. He's got the reassuring shoulder clap down. Every little nuance of this movie is brilliant and surprisingly innovative in spite of the fact that the movie is a spoof. I'm giving credit to the Canadians on this one. I doubt this movie would have been as funny or insane had it been done in the States. Do not miss Invasion! or Top of the Food Chain or whatever it's called in your neighborhood. It is smart, funny and will always be one of my personal all time favorite rentals.
