“Greaser’s Palace,” set mainly in its titular frontier saloon, the domain of a murderous, constipated tyrant known as Seaweedhead Greaser (Albert Henderson), features spectacular New Mexico scenery and a cast of scuzzy varmints. On one hand, it’s a hippie anti-western in the tradition of “Little Big Man,” “The Last Movie” and “El Topo,” which, as an incomprehensible parable about a showbiz messiah, “Greaser’s” appears to parody. On the other hand, it’s a movie that flaunts gags so daringly unfunny it might have been Andy Kaufman’s bible.
