Dongboy: Look out for Ewan McGregor in Velvet Goldmine and The Pillow Book - nice big one!
Apparently there's a really huge, horse-hung guy named Daniel Freire in the new Mexican film Sex and Lucia.
Also look out for
Joe Dallesandro in Trash and Flesh
James Woods in The Onion Field
Mark Gerber in Sirens
Kieran OBrien in Virtual Sexuality (whoa!)
Kip Pardue in Rules of Attraction
Jean-Hughes Anglade in Betty Blue
Vincent Perez in La Reine Margot (Queen Margot)
ERIC BANA in Chopper (massive!)
There were also some unknown nude extras and bit-players in Pier Paolo Pasolinis films The Canterbury Tales and Salo: 120 Days of Sodom who were chosen specifically because they had giant, enormous horse-dicks that hung down close to their KNEES! Truly, these studs sizes have to be seen to be believed. Happy "viewing"!
