Martin's recent roles include portraying Verna The Secretary in Dumbo. According to Martin, she met Dumbo director Tim Burton back in the Beetlejuice days because her friend, Glenn Shadix, played Otho in the film. The two reconnected after Ben Davis, director of photography for both Three Billboards Outside Ebbing, Missouri and Dumbo, suggested Martin to Burton for the role of Verna.

In the HBO series Big Love, Martin's character, Selma Green, is the sibling of polygamous cult leader Roman Grant and first wife of Grant's rival polygamous cult leader, Hollis Green. The character of Green sparked much discussion on fan forums due to her masculine gender presentation and expression, and unusual relationship with her husband (who refers to Green as "Brother Selma").
