Paramount Pictures is releasing "Jackass 2.5," a collection of outtakes and unreleased material from the feature film "Jackass: Number Two," online only next week through Internet movie service Movielink.

This is being billed as the first major studio-backed feature-length release in a Web-only format, and Paramount appears to be testing the waters as to whether or not this is a formula for online movie success.

Movielink, which is owned by Blockbuster, will offer exclusive access to the movie for a week. Viewers can stream the movie for free (if they are willing to sit through short ads). Then, anyone that wants will be able to download the film on iTunes or Amazon.com for somewhere between $10 and $15. The studio will also release a $30 DVD version.

Coinciding with Wednesday's launch, MTV Networks (which, like Paramount, is a subsidiary of Viacom) is launching a new Web site — jackassworld.com.

Will this work? Who knows? I know I wasn't the only one baffled when "Jackass: Number Two" opened at the top of the box office in 2006.

One thing is for sure, though — Johnny Knoxville definitely is up to the same old same old.

A studio exec involved with the project told the New York Times about "2.5," "There's more vomiting, nudity and defecation."
