I have read that "Williams'" is correct, "Williams'" is a myth and that both are fine (but pronounced differently). ;)

We should probably have consistency but from the official side there's Indiana Jones' Greatest Adventures and, if memory serves, I got "Indiana Jones's Satchel" from the now defunct Indiana Jones Adventure World.
