When he took on the title role in Shakespeare's Richard III in 2015, one critic wrote "Jon Mullich is one of the best 'Richards' we have seen, teetering a tight line between portraying madness, histrionics and unbridled ambition.

It takes a studied actor to show the human side of Richard without giving in to the buffoonery of his folly and Mullich owns the character both body and soul.

"[5] Mullich's work as a playwright includes an adaptation of Carlo Goldoni's farce A Servant of Two Masters which transferred the action of the play to Prohibition-era Chicago.

Mullich also played the role of Truffaldino Bottachio as a Brooklyn wise guy in the premiere production, a performance that Back Stage West[6] said "keeps the audience roaring with laughter at his shameless mugging".

It included such non-G&S elements as a talking computer, a lizard man, and an alien probe, and also featured Gilbert & Sullivan songs from The Mikado and The Yeomen of the Guard.
