Halle and Aykroyd Frolic in Vegas, ‘The Hangover’ Crew Hits New York

There were parties aplenty before the holiday weekend began

Halle Berry and Dan Aykroyd were amongst the surprise names popping up at the grand opening of the new Nikki Beach inside the Tropicana in Las Vegas Thursday night.

Aykroyd promoted his Crystal Skull vodka, popular because it comes in a spherical glass skull instead of a traditional bottle. Local L.A. affiliate Fox 11 sent a crew all the way up to the busy Memorial Day destination for live hits from the long party. Meanwhile back in L.A., the Fox network held post-upfront screenings for international buyers.

It’s not all fist-pumping and teen pregnancy at MTV. The network celebrated its continuing push in to scripted series with a premiere party for the new “Teen Wolf” series at the Roosevelt on Wednesday night. The series, a revamp on the 1985 Michael J. Fox film, premieres immediately following the MTV Movie Awards on June 5.

MTV gave the same push to its first scripted series last year, “The Hard Times of R.J. Berger,” debuting it as the Movie Awards lead-out.

“The Hangover Part II” crew started this lucrative week in New York City for a slightly more subdued screening with the Cinema Society than their Hollywood blowout last week. (At the L.A. bash, they had a creative “Thai-in,” bringing on sponsor Tabasco to provide every departing party-goer with a hangover cure bloody mary kit. Zach Galifianakis was the last to call it a night.)

The salad of talent at this premiere was a varied as the still photos in the credits: Bobby Flay, Ivanka Trump, James Van der Beek, Calvin Klein, Charlotte Ronson, NHL headline grabber Sean Avery, and Gabourey Sidibe amongst others. Microsoft’s Bing, which continues to open the wallet to sponsor at least one high profile event a week, put on the premiere and after-party at The Top of the Standard.

The “wolfpack” then moved on to Berlin for another premiere on Wednesday night, a city whose boring reputation makes it a very unlikely candidate for “The Hangover Part III.”
