What About Bob? is a 1991 American comedy that delivers non-stop laughs through a brilliantly simple premise. The film follows Dr. Leo Marvin (Richard Dreyfuss), a successful but self-important psychiatrist who's about to enjoy a peaceful family vacation and national television fame. His plans are spectacularly derailed when his most dependent patient, the charmingly neurotic Bob Wiley (Bill Murray), tracks him down, refusing to be left behind.

Bill Murray's performance as Bob is a masterclass in comedic timing, blending childlike innocence with relentless persistence. His mantra "baby steps" becomes both a therapy technique and a weapon of mass disruption as he ingratiates himself with Dr. Marvin's family while driving the doctor to the brink of insanity. Richard Dreyfuss provides the perfect straight-man counterpart, his escalating frustration creating superb comedic tension.

Directed by Frank Oz, the film excels in situational comedy, mining humor from the clash between Bob's oblivious neediness and Leo's controlled professional life. The supporting cast, including Julie Hagerty as Leo's wife and Charlie Korsmo as his son, add warmth and additional comedic layers.

Viewers should watch What About Bob? for its timeless humor, iconic performances, and the sheer pleasure of watching two comedy legends at their best. The film's exploration of therapeutic boundaries, family dynamics, and what truly constitutes mental health remains surprisingly relevant, all while delivering constant laughs. It's a vacation comedy where the vacation goes wonderfully wrong in the most entertaining way possible.
