Editor's note: We assume you've already seen the movie, but just in case you landed on our Harley Quinn Suicide Squad collection page because you like gorgeous blondes. . .no spoilers here! We'll just say that the HQ of Suicide Squad is Harley Quinn on steroids: she's every bad little girl who ever put on her best party/church dress and went straight out to play in the mud. And then came back inside with a smile on her face and no regrets. Get your Harley Quinn Suicide Squad wallpaper today and don't worry about getting mud on your best dress, as long as you had fun!
