Ritchie directed a 20-minute short film in 1995 entitled The Hard Case. His first full-length feature was the successful Lock, Stock and Two Smoking Barrels in 1998. Recalling Quentin Tarantino, The Sting and The Italian Job, the film was widely praised for its wit. It also introduced actor Jason Statham (The Transporter) to worldwide audiences, and introduced former football player Vinnie Jones to a new career as a film actor. In 2000 Ritchie won an Edgar Award from the Mystery Writers of America for Best Motion Picture Screenplay.
His second feature film was Snatch, released in the year 2000.

The cast featured such Hollywood big names as Brad Pitt, Benicio del Toro and Dennis Farina, along with the returning Vinnie Jones and Statham.
Following his marriage to Madonna, Ritchie began focusing his filmmaking on his famous wife, directing her in both a music video (for the song "What It Feels Like for a Girl," a controversial video that showed Madonna engaging in running people down with a car) and a short film, "Star", for the BMW films series. Ritchie's next film, also featuring Madonna, was a remake of the 1974 Lina Wertmüller hit Swept Away (also entitled Swept Away). This film was both a critical and commercial disappointment.
Ritchie's next project was a Vegas-themed heist film entitled Revolver, which was critically panned.
