Costing $600 each, two films by experimental director Ken Jacobs share first place for the top slot on Amazon Instant Video. "Tom, Tom" is a 1969 avant-garde rephotographing of a 1905 film of the same name, and "Ontic Antics" is a 1997 reworking of the 1929 Laurel and Hardy film "Berth Marks."
If $600 seems a bit steep for digital editions of remixed old movies, you can always get a one-week rental from Amazon for a mere $275.
If you're still not sure whether it's worth the investment, here's the first couple moments of "Ontic Antics."
