The official Palindromes website is now up, though at the moment it's still a content-less hold page that says,
A Film by Todd Solondz
...See for yourself at: www.palindromes-movie.com I've added it to the links on the main page... Hopefully there'll be something a bit more substantive there soon.
Also, IFilm has posted the official Palindromes theatrical trailer, along with three one-minute clips from the film. Check 'em out at: http://www.ifilm.com/ifilmdetail/2653502?htv=12
"Props" to John for finding these.
