In Sabrina the Teenage Witch, Mull played Sabrina’s (Melissa Joan Hart) blundering high school principal Willard Kraft.

Hart, 48, posted an Instagram tribute to Mull, who portrayed the principal for 73 episodes between 1997 and 2000.

‘Rest in Peace, my friend. The incredible #MartinMull (Principal Kraft) has left us for his eternal rest,’ she wrote.

‘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.’

The former child star added that even after their time on Sabrina the Teenage Witch, the two actors kept running into each other on numerous TV sets throughout the years.

‘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,’ she wrote.

She sympathised with his family at losing a ‘wonderful man’.

‘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. He will be missed, but this world has benefited from his being here,’ she wrote.

Actor and Jennifer Tilly, who starred alongside Mull in the 1988 movie Rented Lips, also paid tribute to a man she remembered as ‘wonderful.’

‘So sad to hear of the passing of Martin Mull. I worked with him a long time ago on a film called Rented Lips that he wrote and also starred in,’ Jennifer shared on X.

‘He was such a witty, charismatic and kind person. As an actress just starting out, it really meant a lot to me to be able to work with such a wonderful actor.’
