‘He was my cheerleader from the get-go and consistently kept me positive with enthusiasm and humor.’

Mayim added: ‘Ash will be missed deeply and it won’t be the same moving forward without him.’

Since the news broke, tributes have been pouring in for the star, including one from Christian’s producing partner Jordan Yale Levine of Yale Productions, who write: ‘In complete shock. RIP to my brother @ashchristian.

‘This doesn’t make any sense to me. You had so much more life to live. We’ve shared so many great memories over the years that I’ll never forget.

‘I love you and will miss you very much.’

While his producing partner Anne Clements added (via Variety): ‘Ash was a great friend, colleague and partner in crime. He was a champion of indie film and filmmakers and his love of the process of putting movies together was infectious.

‘My heart goes out to his family, especially his mother. The world lost one of the good ones.’
