For Supernatural fans, Mark Pellegrino will always be Lucifer, and that’s why Misha Collins felt so much pressure when the show came to him with the idea that Lucifer would inhabit Castiel’s vessel. “It was very daunting because I think Mark Pellegrino is like the best actor that we’ve had on the show, so for me to have to play the same character that he’s been playing in a similar manner that he’s been playing is a real challenge,” Collins tells EW. “I think it’s an exercise that’s designed to make me look bad,” he adds with a laugh.
