Bryan Cranston is remembering his late Breaking Bad costar Mark Margolis.

On Friday, the 67-year-old actor said he was “very saddened” by Margolis’ death in a poignant tribute on Instagram.

“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,” he wrote alongside photos from both television shows.
