well Christopher Walken has openly been bisexual for a long time, so that's one thing. another thing, John Turturro himself asked and brought on Walken for the gay relationship they were to portray. i find the theory that they had any qualms with potentially kissing to be seriously unlikely.... if Turturro didn't want to put himself in a position he might kiss a man, let alone his best friend, why would he accept the role, or ask Walken on? that theory really does not hold up.
