The PhilaMOCA-curated ode to alternative, odd and nontraditional filmmaking makes its return for a multi-week run, shedding light on aspects of the medium that typically don't get much love — like VHS tapes or a fan adaptation of "Raiders of the Lost Ark." The third annual Cinedelphia Film Festival runs from Thursday, April 9 through Saturday, April 25 with all events taking place at PhilaMOCA (531 N. 12th St.). Here's a taste of what to expect.

Screen a not-yet-completed locally filmed and produced documentary, "Vietnam Appreciation Day," at the festival's kickoff on Thursday, April 9. Centered on 23-year-old Bubba, who finds himself in the midst of participating Vietnam War reenactments after his own goals of military involvement could not be fulfilled, the film screens at 7:30 p.m.

Rock 'n' roll never dies. Ten years ago, the Paul Green School of Rock Music documented young musicians in the doc "Rock School." See the film, find out what those kids are up to now, and hear them perform at 7:30 p.m. on Saturday, April 11.

It's a double dose of horror on Wednesday, April 15, when two 1970s Creature Features, starring Spanish actor Paul Naschy, screen starting at 7:30 p.m. They're going all out, too: See both "The Mummy's Revenge" and "The Fury of the Wolfman" as they would've aired on TV — with vintage commercial breaks.

You know those awful sci-fi flicks that are just too ridiculous to be true? The Academy of Natural Sciences does, too. Experts from the museum come to PhilaMOCA on Thursday, April 16 to dispel some of the "science" in  "Giant Octopus," starting at 8 p.m. Come an hour prior for snacks and live animals and hang around after for a killer animal movie-themed trivia game, starting at 9:30 p.m.

This is dedication. Over the course of seven summers, two adolescent boys re-created "Raiders of the Lost Ark" line-for-line — save for one scene — starting when they were just 11 and 12 in 1982. They finally finished the fan film and you can see it on Friday, April 17 at 7:30 p.m.

Put the brakes on the films for an evening of director-based burlesque starting at 10 p.m. on Saturday, April 18. Inspired by the directorial work of Terry Gilliam, Miss Rose's Sexploitation Follies features acts paying homage to "Brazil," "The Imaginarium of Doctor Parnassus," "Fear and Loating in Las Vegas," and "Time Bandits."

A fascinating beast, the young-adult, coming-of-age story is one that deserves a detailed look. Come Thursday, April 23, you'll be forced to relive your awkward years through clips of over 200 teen movies in "Beyond Clueless," at 7:30 p.m.

A predecessor to the hilarious Vines and Instagram videos of current day, Len Cella's "Moron Movies," 60-second or less comedic short films that became a regular occurrence on "The Tonight Show Starring Johnny Carson," are highlighted on Friday, April 24. Grab a good seat, the show starts at 7:30 p.m. — and will be attended by creator Len Cella.

So bad, its good. This marathon on Saturday, April 25, requires no training except a high tolerance for terrible movies … which you'll be watching for 12 hours. With highlights like "Troll 2" and "The Skid Kid," you'll need enough stamina to take you from 7:30 p.m. to 7:30 a.m.

Don't miss out on the rest of the festival's one-of-a-kind events. Cinedelphia's full schedule is here.
