The newest Comic-Con International: San Diego exclusive is pretty serious, at least for a Jack in the Box. Entertainment Earth announced their booth will be home to a retro-styled Jack in the Box from Big Bang Pow! featuring Heath Ledger's Joker from 2008's "The Dark Knight".

The con-exclusive collectible, which retails at $49.99, measures five-and-a-half inches tall by five-and-a-half inches wide. It features a plastic head sculpted by 3D Systems, AKA Gentle Giant, along with a playing card themed exterior complete with the Joker's signature "Why so serious?" quote.

Ledger's unforgettable performance in the Christopher Nolan-directed film earned him an Academy Award for Best Supporting Actor and numerous other accolades. After completing work on the film, he died as the result of an accidental overdose. Many have wondered what Nolan's third Batman movie would have looked like if Ledger had been available, though there were never concrete plans to bring the Joker back.

Entertainment Earth's booth (#2343) will also feature a "Dexter" pin mate wooden figure, a "Batman v Superman" Jokers Wild Batman 19-inch action figure and more merchandise from properties like "The Twilight Zone"," "Star Trek," "The Big Bang Theory" and more.

All of Entertainment Earth's convention merchandise is available for pre-order on their website, with orders filled and shipped should merchandise remain after SDCC.
