Full frontal would have been a kind of deliberate cut, to see that for no reason.
According to the director of the third and final Fifty Shades film, James Foley, Jamie — who plays Christian Grey — filmed a couple of scenes from Freed totally butt-naked.
It just becomes sort of gratuitous if we don't need it.
But in the final cut, I'm being totally honest, it just didn't come off.
Especially now that we know that there is actual footage of a 100% naked Jamie Dornan from Fifty Shades Freed somewhere just waiting to be found.
