Sony/Columbia’s adaptation of Dan Brown novel “Angels and Demons” brought in $152.3 million worldwide in its opening weekend, including a No. 1 opening at the US box office with $48 million from 3,527 theaters.

“Angels and Demons” was released as a 4K DCP, per a 2008 Sony plan to release the majority of its filmed productions in the 4K format. “Salt” and “The Green Hornet” are among the expected upcoming 4K titles.

Interesting timing, since word is spreading that Regal chose Sony 4K digital cinema projectors for its circuit (see Celluloid Junkie post below). 2K DCPs are the most commonly used. With AMC and now Regal planning to go with 4K projection, will a shift to more 4K DCPs be on the horizon?

Meanwhile, Regal’s rollout schedule—when revealed–may serve as an indicator of when the 3D screen availability might begin to loosen up.

Dreamworks Animation’s 3D “Monsters vs. Aliens” continued to perform in its eighth week. The title finished seventh for the weekend, earning $3 million in 1,951 theaters and bringing its domestic total to $190.5 million. It has reached $333.5 million worldwide.

“Monsters” had two weeks to go before Disney/Pixar’s “Up” grabs the 3D ready screens for its May 29 opening. “Up” is Pixar’s 10th CG feature and first in digital 3D.

Meanwhile, Paramount’s “Star Trek” has climbed to $147.6 million in North America and $196.9 worldwide, and “X-Men Origins: Wolverine” has reached $151.1 million in the domestic market and $274.1 worldwide. Onion News Network offered its take on the “Star Trek” release, see below:

Release News: A remake of the 1984 musical “Footloose”—sans casting news—has been given a release date: June 18, 2010. We’re going to assume that there won’t be an announcement that it will be filmed in 3D, as the “Footloose” redo will share its release date with Disney/Pixar’s “Toy Story 3.”
