My favorite one is "A Tiger" by Catalan artist Dionis Escorsa. You can find it on his web-stie. I've shown this film on my filmfestival in Berlin (WIPE amateur film festival). Now I'm organizing here in Berlin another festival dedicated only to the films made using the technique of photomontage. Check the web-site of WIPE in oder to find the form for application. Firts edition will happen this winter.
