Ten years isn't a long time in the world of film festivals. Take, for example, the Cannes Film Festival which will celebrate its 64th year next month, or Venice, which is pushing 68 this fall. But in a decade's time the Tribeca Film Festival has been able to impress many as it has nudged itself into the extremely crowded spring festival season.

As you probably know by now, the festival was created in 2002 by Robert De Niro, Jane Rosenthal and Craig Hatkoff as a four-day fest to bring business back to Lower Manhattan after the attacks on Sept. 11, 2001. Since then it has grown to 12 days filled with red carpet premieres, panels, outdoor screenings and a day-long kids fair, while expanding from its original eponymous roots to the Chelsea neighborhood of Manhattan as well as the Lower East Side.

In celebration of Tribeca's 10th anniversary taking place April 20–May 1, the opening night film -- Cameron Crowe's documentary on Elton John, 'The Union' -- will have a free outdoor screening in Manhattan's Financial District as well as a performance by the Rocket Man himself. (Learn more about attending opening night here.) And if you can't make it to New York to see the fest firsthand, Tribeca has you covered. This year they've created Tribeca (Online) Film Festival, where you can watch select films online as well as video streams of live events. Select titles will also be available on video-on-demand.

Here's 20 films that's worth checking out at this year's fest. Which are you most excited to see?
