Mr. Monk’s Last Case: A Monk Movie
Tony Shalhoub as Mr. Monk
A former homicide detective at SFPD, Adrian Monk now works as a consultant for the department. He is brilliant, sharp, extremely observant, with fine detection skills. However, he is also highly eccentric, besides suffering from severe obsessive-compulsive disorder coupled with a laundry list of fears and phobias. He is known to have 213 things that are significant phobias for him, including germs, enclosed spaces, heights, milk, and ladybugs. His condition worsens with the sudden death of his wife, Trudy, who was killed by a car bomb. Following a nervous breakdown, Monk loses his job and withdraws from life. But with the help of his nurse and assistant Sharona Fleming, (who was replaced by Natalie Teeger in later seasons) the detective gets back on his feet.
Monk ends up as a consultant for the San Francisco police, solving crimes and bringing justice. But he also makes it a mission to investigate Trudy’s death, which forms the underlying arc for the series. His OCD and phobias might be reasons of frustration for everyone around him but they also help him with attention to detail and spot the minutest details others might miss, thus working in his favor for solving crimes. Despite all his quirks, his big heart, obtuse but incredible sense of humor, and refreshing outlook on grief and trauma are what makes Monk an endearing man.

Emmy, Tony, and Golden Globe-winner Tony Shaloub reprises his award-winning, iconic role of detective Adrian Monk for the upcoming movie. Shaloub portrayed the titular role through eight seasons of the series, followed by a Covid-19 special,Mr. Monk Shelters in Place, in 2020.
