I made an app called 'Friends with Benefits' (fwb-game.com) and soon found out that Justin Timberlake has a new movie (fwb-movie.com) coming out in a few months time with the same title. So I decided that it might be a good idea to repackage my app a little bit to leverage the exposure that the movie will get. But I'm not sure if I've gone too far. The logo, for example, using the same color scheme, but I didn't copy it exactly from them, I used a slightly different font. I'm just wondering if what I did will get me in trouble.
