Ready for another round?

Warner Bros. has released a teaser for the much-anticipated sequel to 2009 box office smash, "The Hangover."

Bradley Cooper, Ed Helms, and Zach Galifianakis reprise their roles in "The Hangover: Part II" with director Todd Phillips returning at the helm.

This time, the "Hangover" troupe find themselves in Bangkok, Thailand, for Stu's wedding.

Written by Phillips, Scott Armstrong, and Craig Mazin, "The Hangover: Part II" is one of several R-rated comedies on the horizon. WB's "Horrible Bosses," starring Helms, Jennifer Aniston and Jason Bateman opens July 29 while Columbia's raunchy laffer "Bad Teacher," which stars Cameron Diaz and Justin Timberlake, bows June 24.

"The Hangover: Part II" hits theaters May 26.

Columbia has released the first teaser for raunchy comedy "Bad Teacher," starring Cameron Diaz and Justin Timberlake.

***Warning: This red-band clip (below) features Diaz swearing more in two minutes than an entire episode of "Hell's Kitchen." ***

Directed by Jake Kasdan, "Bad Teacher" tells the story of a gold-digging middle-school teacher (Diaz) who competes with a colleague for the affections of the school’s model teacher (Timberlake).

"The Office" scribes Lee Eisenberg and Gene Stupnitsky wrote the screenplay.

Produced by Jimmy Miller and Georgia Kacandes, "Bad Teacher" opens wide June 24.

Paramount has released an extended trailer for Marvel's 3D tentpole "Thor."

Directed by Kenneth Branagh and starring Chris Hemsworth and Natalie Portman, "Thor" tells the story of a partly disabled med student who discovers his Norse god alter ego and soon rekindles an Ancient war. Anthony Hopkins also stars.

Opening wide May 6, "Thor" will likely reign at the box office until Disney's fourth "Pirates of the Caribbean" bows May 20. "Thor," which was originally supposed to get a May 20 release before Sony decided to reboot "Spider-Man," was produced by Marvel's Kevin Feige.

Marc Graser reports on what's in store for Disney, live via Twitter.

Variety's Steven Gaydos is in Berlin, where he spoke to someone who has seen 25 minutes of Martin Scorsese's upcoming "The Invention of Hugo Cabret."
 
Said our source: "This is the beginning of 3D."
 
The 1930s-set pic is Scorsese's first 3D movie. Cast includes Ben Kingsley, Sacha Baron Cohen, Emily Mortimer, Ray Winstone, Jude Law and young Asa Butterfield as the eponymous Hugo.
 
2011 is shaping up to be a year that 3D becomes a "respectable" tool for "serious" directors, with Werner Herzog's "Cave of Forgotten Dreams," Wim Wenders's "Pina" and Scorsese's "Hugo Cabret" all due for release by year's end.
 
In other 3D news out of Berlin, the news that a cache of Nazi-era 3D footage had been found in a German archive sent us scrambling to learn more.
 
Variety's archives from the period mention a 3D system developed by Swiss inventors Jacques and Emil Burchardt in the late 1920s and another demonstrated in 1936 by no less than Louis Lumiere, who with his brother invented motion pictures as we know them, but neither appeared to be the system used for the German "raum film" movies.
 
And in fact 3D expert and author Ray Zone confirms that the Nazis were using another system altogether:

"I wrote about the single strip 35mm 3D system developed by Otto Vierling in 1935 that was used by the Third Reich to shoot WWII films (over 300,000 feet of footage) in my history 'Stereoscopic Cinema and the Origins of 3D Film: 1838 - 1952.' Film frames showing the format are reproduced in the book. In 1936 the Berlin Olympics were actually shot with Zeiss high-speed dual 16mm 3D. The first sound color 3D motion picture, 'Close Enough to Touch' (Zum Greifen nah), a promotional short, was shot with Vierling's system on Agfacolor film and premiered in Berlin in May, 1937.
 
"The Berlin footage was recovered in 1994 from the ruins of a church that was bombed in Dresden and copied from nitrate stock to modern film material by the Cinema Film Division of the Federal Archive in Berlin.

"Lots of stereoscopic production in Germany in the 1930s."

Variety caught up with the Zeiss system in 1953. On April 7 that year, Daily Variety ran this news item:

King Brothers To Use German 3-D Process

King Bros, have arranged to act as American distribs of a new German 3-D process developed by the Zeiss Ikon Co., of Stuttgart, prexy Frank King reported yesterday, following his return from a month's trip to Europe.

Only a single strip of film is used In this new process, and a single projector, but polaroid glasses are required to view the picture. A prism Is utilised in the camera, instead of mirrors, King said, and a special device is attached to projector's lens to give the 3-D effect.

The stereoscopic process already is ready, but Zeiss is working on the stereophonic sound, King stated. This Is nearly completed, however, and will be ready within the next 60 days. Kings will first use the new Zeiss Ikon process on "Two Headed Spy," which they will produce In Germany after they finish "Carnival," slated to roll at the Gelselgastelg Studios in Munich June 1. King completed production and financial arrangements for the two films during his stay abroad.

"Carnival" will be made in an American 3-D process, King declared last night, since the Zeiss process won't be ready in time. Film will be made In both English and German versions, with principals taken from Hollywood to Germany for the English version and German thesps employed for the native version. Story revolves around experiences of an American carnival troupe travelling through present-day Germany.
