Go is a 1999 American crime comedy film written by John August and directed by Doug Liman, with intertwining plots involving three sets of characters. The film stars William Fichtner, Katie Holmes, Jay Mohr, Sarah Polley, and Scott Wolf and features Taye Diggs, Breckin Meyer, Timothy Olyphant, Desmond Askew, Jane Krakowski, J. E. Freeman, and Melissa McCarthy in her film debut.

The film is set around Christmas. Ronna Sarah Polley, a clerk at a grocery store, is facing eviction if she doesn't come up with "more money then she has." While at work, Ronna is propositioned by two actors ( Scott Wolf and Jay Mohr )for drugs, Ronna comes up with an idea to score drugs from dealer Todd Gaines Timothy Olyphant and sell them at a higher price in order to pay her rent. Ronna's plan goes array when she realizes that she is caught up in a sting. Disposing of the drugs in order to avoid arrest, Ronna finds herself in an even worse financial situation. To recoup her losses, Ronna makes the decision to return allergy pills to Todd and say that her deal fell through. From here, three wild and amusing stories intertwine.

The film underperformed at the box office but was critically acclaimed.
