The Dark Knight isn't the only thing that's rising this week - so are ticket prices to see the new Batman flick, which debuts Friday, July 20.

With midnight showings and IMAX screenings of "The Dark Knight Rises" having sold out in some markets weeks and often months ago, fans are turning to Craigslist and eBay, and some sellers are asking big bucks for tickets.

An eBay seller in Los Angeles is asking $125 a ticket while another in Council Bluffs, Iowa, wants $140. An eBay seller in L.A. is offering two tickets to a 7 p.m. screening for $300.

Review: "The Dark Knight Rises"

The majority of people are selling tickets for mostly regular screenings in the still-overpriced $25 to $40 range.

It may be a good idea to check with your local theater before shelling out big bucks for the flick. A Craigslist seller in NYC is asking $100 a ticket for a midnight screening, but the AMC Theater in Times Square as of Tuesday still had seats available for a 12:07 a.m. show.

Reviews for the movie have been less than kind, prompting one review site to disable its comment boards after site visitors flamed the reviewers.
