All Good Things is a 2010 American mystery/crime romantic drama film directed by Andrew Jarecki and written by Marcus Hinchey and Marc Smerling. Inspired by the life of Robert Durst, it stars Ryan Gosling, Kirsten Dunst, and Frank Langella. Gosling portrays the wealthy son of a New York real estate tycoon (Langella) who develops a disturbing relationship with his wife (Dunst) and becomes suspected of a series of murders, as well as his wife's unsolved disappearance.

All Good Things was filmed between April and July 2008 in Connecticut and New York. Originally scheduled for a July 24, 2009 release, the film ultimately received a limited release on December 3, 2010.

Durst professed admiration for the film, and after previously not cooperating with journalists, offered to be interviewed by Jarecki. Durst would ultimately sit with Jarecki for more than 20 hours over a multi-year period, which led to the true crime documentary series The Jinx in 2015.
