Shia LaBeouf’s short film HowardCantour.com lifts visuals, dialogue, and script from Daniel Clowes’ short comic story "Justin M. Damiano" without permission or attribution, according to Buzzfeed.  The film short has verbatim dialogue lifted from the comic story as well as many story parallels.  It premiered at the May 2012 Cannes Film Festival.  

Clowes told Buzzfeed he’d never spoken to or met LaBeouf and had no idea there was a film based on his work until he received a link on Monday.  

Clowes’ story was originally published in The Book of Other People, a Penguin anthology edited by Zadie Smith, and also appeared in Best American Comics 2009

Later Monday, LaBeouf tweeted, "In my excitement and naivete as an amateur filmmaker, I got lost in the creative process and neglected to follow proper accreditation."  No mention of the permission he forgot to get or the payment he forgot to make, although he concedes "I f***ed up."
