Which film was George Clooney's directorial debut?

"Confessions of a Dangerous Mind" is a 2002 biographical spy comedy film depicting the fictional life of popular game show host and producer Chuck Barris, who claimed to have also been an assassin for the CIA. The film was George Clooney's directorial debut, was written by Charlie Kaufman and starred Sam Rockwell, Julia Roberts, Drew Barrymore, and George Clooney himself.

Columbia Pictures had planned to produce a film adaptation of Barris's 1984 "unauthorized autobiography" of the same title in the late 1980s. When the film rights were purchased by producer Andrew Lazar, Kaufman was commissioned to write a new script, which attracted various A-list actors and filmmakers to the project. Bryan Singer at one point planned to direct the film with Johnny Depp in the lead role, but the production was canceled. The production resumed when Clooney took over directing duties.

Barris remained heavily involved in the production in an attempt to portray the film from his point of view. To accommodate the $30 million budget, Clooney convinced Drew Barrymore and Julia Roberts to lower their salaries. The film was released to respectful reviews from critics and was modestly successful at the box office. Rockwell, in particular, was praised for his acting and won the Silver Bear for Best Actor at the 2003 Berlin International Film Festival.
