Are you ready for a sneak peek at tomorrow's blockbusters today? Check out our new series "Behind the Screen" Sunday night at 11 p.m. on MTV for the broadcast premiere of the "Brüno" trailer, the very first visit to the set of Russell Brand's "Get Him to the Greek" and much more!

Director Shawn Levy wants to make one thing abundantly clear: [artist id="2088128"]The Jonas Brothers[/artist] are not in [movie id="375855"]"Night at the Museum: Battle of the Smithsonian."[/movie] Well, not really ...

Eagle-eyed theatergoers may notice that three angelic cherubs bear a striking resemblance to a certain pop trio. The characters make their initial appearance as cupids, hovering over [movieperson id="99943"]Ben Stiller's[/movieperson] onetime night watchman and his budding love interest, Amelia Earhart, played here by "Enchanted" beauty [movieperson id="238473"]Amy Adams[/movieperson]. The flying statues aren't a complete match for the JoBros, but their true alter egos are clearly revealed when they break into lines from "Lovebug."

While the cherubs were always intended to be in the film, Levy explained the reason for the Jonas' inclusion lies close to home. "I'm a father of three daughters, so the Jonas Brothers are definitely in my wheelhouse and in my literal house," he said. "But I knew I wanted it to be subtle."

Levy is careful to point out that the cherubs make up only one part of an extensive cast of characters, ranging from [movieperson id="103539"]Robin Williams'[/movieperson] Theodore Roosevelt and Bill Hader's General Custer to Hank Azaria's villainous Egyptian pharaoh. In this sequel to the 2006 [article id="1549412"]smash hit[/article], Stiller heads to Washington, D.C.'s iconic museum as a one-man rescue party for his magical friends.

The filmmakers took pains to match each famous face with the appropriate actor and, in the case of the Jonas Brothers, it was love at first sight.

"I needed three guys who could sing really well, and it just seemed like a good fit," Levy said. "There's a huge overlap in the fanbase for this franchise and their fanbase."

Both Levy and the brothers themselves are careful to label their participation as a brief cameo and nothing more. "The guys didn't want it to be like, 'The Jonas Brothers in ...,' " explained Levy. "So it's three cherubs who are not so much literally twins of the brothers but, in that one of the cherubs has straighter hair, I suppose it's unavoidable. But it remains just a cool thing they did for the fun of it. It's just kind of a little Easter egg for viewers who care to notice."

The director manages to sum up the singers' Smithsonian excursion simply enough. "I don't want to mislead anyone: The Jonas brothers are not in the movie, but they are the voices and the models for three marble naked babies."

"Night at the Museum: Battle of the Smithsonian" marches into theaters Friday.
