Actually, that's not necessarily true. What he doesn't want is you looking at pictures of him in his underwear that he claims are actually just his head Photoshopped onto someone else's body... and he's willing to take legal action to make you stop.
Lawyers for the actor have sent letters to various websites, including Buzzfeed.com, asking for the photo to be removed because the image violates his legal rights, ""portraying him in a false light, violating his right of publicity and constituting a false designation of origin in violation of the Lanham Act."
The letter says that, "as anybody could tell from a cursory examination, this is a fake picture, in which our client's head has been pasted on the body of another person." Will the letter having the opposite effect from its intended one ? Admit it, you want to see the image more now than you did before, don't you? As Queerty.com, which received one of the letters, put it, "their letter bumped it from 'funny and cute' to 'actually newsworthy'." I can't help but wonder why this suddenly seemed like a good idea to either Gyllenhaal or his legal team.
The internet is filled with Photoshopped fakes of celebrities, many far, far worse and more "violating" than this particular image, and no-one takes them seriously. What is so terrible about this one image that it requires this kind of overreaction? I'm imagining somewhere, some big name director talking to him and saying "I was all ready to give you this big role, and then I googled you and saw you in your white boxers and thought, nah, maybe not."
