Bryan Cranston Instagram – I am very saddened today to learn of a friend’s passing. Mark Margolis was a really good actor and a lovely human being. Fun and engaging off the set, and (in the case of Breaking Bad and Your Honor) intimidating and frightening on set. His quiet energy belied his mischievous nature and curious mind… And he loved sharing a good joke. I miss him already. Rest now, Mark and thank you for your friendship and your exceptional body of work. Photos: 1. Your Honor 2. Breaking Bad
