Found these on YouTube. They might be in some other thread, but I saw them and had to make sure they were here. Great interviews with the cast, including new cast members, and Sylar with a puppy? Zach fangirls...you're welcome!

These are too funny, especially with Kristen Bell and Zachary Quinto, and David Anders is pretty funny too! Hope you check them out!
