The Green Lantern star loves locking eyes with rescue dog Baxter – in fact, it's how they met. "I saw this big, dumb-looking retriever staring up at me," he told PEOPLE of finding his dog at a Houston animal shelter. "I whispered to him, 'Hey, let's get the hell out of here.' ... [And] he came with me, he jumped in the car, and we've been best buddies ever since."
