It's going to be a lot more difficult for him on account of being famous and having his face and accusation plastered all over the media.
For your average non-famous person, a potential employer isn't going to know you've been charged with something (unless they specifically ask and you tell them the truth [which you should]).
For your average non-famous person, there's significantly less reputational risk for an employer to employ them, as they are unlikely to be recognised by customers - if you go into Costa and order your coffee from some random guy who was charged with rape, you're highly unlikely to recognise them, but if it's someone famous who's been all over the media, then there's a much higher likelihood that you will. Most employers aren't going to want that kind of negative association, so it's safer just to say no.
