A comic book fan and filmmaker has launched an online fundraising campaign to help solve the mystery surrounding Tim Burton and Nicolas Cage's aborted Superman movie as images showing the actor in character as the Man of Steel appear online.

Two black and white images surfaced on Twitter.com on Tuesday (29Jan13), showing Cage in a test suit for Superman Lives, the scrapped project that he had worked on with Burton and fellow director Kevin Smith in the 1990s.

Little is known about why the film was shelved, and it remains one of Hollywood's greatest comic book movie mysteries today - but Jon Schnepp is hoping to get to the bottom of the story in a new documentary, tentatively titled, The Death of Superman Lives: What Happened?.

Schnepp created a page on Kickstarter.com last week (24Jan13) and hopes to raise the $98,000 (£61,250) needed to fund his project. He has already attracted the support of 1,132 investors, who have helped him raise over $45,000 (£28,125) with 38 days still to go.

Schnepp is planning to interview as many people involved in the axed movie as possible and recreate scenes from screenwriter Wesley Strick's script, which leaked online earlier this month (Jan13).

The filmmaker hopes to complete The Death of Superman Lives: What Happened? in time to screen at the San Diego Comic-Con International event later this year (13) - around the same time as the release of the new Superman movie Man of Steel, starring Henry Cavill as the titular character.
