"Rest in Peace my friend. The incredible #MartinMull (Principal Kraft) has left us for his eternal rest," she began in the caption, adding, "I have such fond memories of working with him and being in awe of his huge body of work which before #SabrinaTheTeemageWitch included #Roseanne and #MrMom as the projects I knew him from."

She saluted Mull for his appearances on "huge shows as well as features and animation" following his time on Sabrina.

Mull also appeared and starred in shows such as Two and a Half Men, Arrested Development, The Ranch and The Cool Kids. He earned an Emmy nomination for his guest role on Veep in 2016. His film credits include Clue, Far Out Man and Mrs. Doubtfire. Most recently, he had guest appearances in Not Dead Yet, Grace and Frankie and The Afterparty.

In her Instagram tribute, Hart shared how Mull explained why he took so many roles.

"He once told me that he takes every job he's offered just in case the train comes to an end, which in this business tends to halt quickly," wrote Hart. "He was an artist who liked to paint and build things with his hands, a musician and a wonderful man who i am better for knowing. "
