Uncertainty is a 2008 indie crime drama thriller film written, produced, and directed by U.S. independent filmmakers Scott McGehee and David Siegel and starring Joseph Gordon-Levitt and Lynn Collins.

Bobby (Joseph Gordon-Levitt) and Kate (Lynn Collins) are a young couple who have been together ten months.

They can't make up their minds where to go on the Fourth of July,[2] or whether to have the baby, so they decide to flip a coin.

The other storyline takes place in Manhattan (beginning in Chinatown), where Bobby and Kate find a cellphone belonging to a criminal who values it at $500,000.

They try to set up an exchange, but after narrowly escaping pursuit from a killer, Bobby throws the cellphone onto a passing boat.
