Fletch is a 1985 comedy film about a wisecracking investigative newspaper reporter, Irwin Fletcher (Chevy Chase), who writes under the name of Jane Doe. The film was based on the popular Gregory Mcdonald novels and the screenplay was written by Andrew Bergman. The film was directed by Michael Ritchie and released by Universal Pictures in 1985. It was one of three films Chevy Chase starred in that year, alongside Spies Like Us and National Lampoon's European Vacation, which together garnered over $155 million at the box office .

The film has since developed a cult following and was followed by a 1989 sequel, Fletch Lives. A prequel, Fletch Won, is currently in pre-production.

Irwin "Fletch" Fletcher, Los Angeles journalist, really lives for his profession. As Jane Doe, he publishes articles that have caused several heads to roll in the past. Now, Fletch is at it again: In disguise as a bum, he lives at the beach, researching drugs and their dealing. One day, Fletch is addressed by Alan Stanwyk, a rich man, who asks him, the bum, a favour. For the sum of $50,000, Fletch should kill poor cancer-ridden Mr. Stanwyk with a gun, so that his wife will get the insurance money. What the guy didn't think of was Fletch's real profession. Returning into normal life, Fletch instantly takes up research not only to find out that Mr. Stanwyk is healthy as life itself but he also runs into certain connections between drug dealing at the beach, Alan Stanwyk, his private jet, the police and a very expensive piece of Land in Utah.
