Peter Chelsom, director of Funny Bones wrote, "Working with him was a masterclass in comic acting – and in charm. From the outset he was generous." "There's a very thin line between a talent for being funny and being a great actor. Jerry Lewis epitomized that. Jerry embodied the term "funny bones": a way of differentiating between comedians who tell funny and those who are funny." Director Daniel Noah recalling his relationship with Lewis during production of Max Rose wrote, "He was kind and loving and patient and limitlessly generous with his genius. He was unbelievably complicated and shockingly self-aware."
