That looks fake to me.
Fake in what sense? If you mean that a real picture of Helen Mirren has been superimposed upon a real picture of a VHS box from the movie, you're definitely correct. Or ...??
No, there actually were some forward-thinking producers in 1969 who would make giant VHS boxes and have their actresses pose next to them.You're probably one of those guys who think the moon landings were faked too.
Fake in that it looks like mirren's head was pasted on top of somebody else's body
That might be. I never suspected it because Helen does more explicit nudity than that in the film, and her body looks pretty much the same as that (http://www.fakes.net/mirren_helen157.jpg), so it wouldn't make sense to use a fake.But it is possible.
For one thing, James Mason was never that young
