No matter how noble the cause, or small the alteration, he is rewriting history.
As far as I know, the only deviation from fact in the original film was in the shape of the bomb; it was still on the secret list when the film was made.
If Mr Fry doesn't like the unvarnished history, he shouldn't remake the film. He shouldn't remake it anyway - remakes rarely achieve anything other than the tarnishing of the original.
