Tom Cruise's 'Rock of Ages,' Adam Sandler's 'That's My Boy' Look to Take Down 'Madagascar 3'

This weekend "Rock of Ages" and "That's My Boy" open at the Box Office in hopes of beating out last weekend's champion "Madagasar 3: Europe's Most Wanted."

 "Rock of Ages" opens in 3,450 theaters. The New Line cinema film stars Tom Cruise (Mission Impossible), and Alec Baldwin (30 Rock) as aging '80s rockers. Supporting Cruise and Baldwin are Paul Giamatti (Cinderella Man), Catherine Zeta Jones (Chicago), Russell Brand (Arthur), and Malin Akerman (Watchmen). The film, directed by Adam Shankman, hopes to replicate the success of his previous summer musical comedy "Hairspray", which debuted to $27.5 million in its opening weekend back in 2006.

However, the film is not tracking as well as originally expected. Most box office observers believe the film will open in the $20 million range. Others believe it could over perform, since tracking for musicals can be difficult to read. "Mamma Mia" and "Hairspray" suffered the same obstacle but ended up becoming hits at the box office.

The film is apparently appealing primarily to women over 25.

The other film opening is "That's My Boy" starring Adam Sandler (Jack and Jill) and Andy Samberg (Hot Rod).  The comedy is expected to open in the $17 million to $19 million range and opens in 3,030 theaters. Sandler is one of Hollywood's most consistent stars in terms of box office performance as he has scored 12 $100 million movies. However, his last film Jack and Jill was a disappointment and only scored $74.2 million throughout its theatrical release.

"That's My Boy" is rated R and contains raunchy humor that can dissuade family audiences from attending the movie. Nevertheless Sony believes the film will still play to Sandler fans.

Despite the two films opening, prognosticators have the current box office king "Madagascar 3" beat both with $35 million. The film, which opened last weekend with a $60 million gross, has already collected $80 million domestically and $200 million worldwide.

"Prometheus" also enters its second weekend and looks to make at least $20 million.

In the specialty area IFC's "Your Sister's Sister" opens in limited release starring Emily Blunt (The Adjustment Bureau), Rosemarie Dewitt (Rachel Getting Married) and Mark Duplass (Humpday). Focus Features "Moonrise Kingdom" will expand to 178 theaters after grossing $4.4 million in limited release. Meanwhile Sony Classic Pictures "Hysteria" starring Maggie Gyllenhaal (The Dark Kinght) will expand to 270 theaters after a disappointing $700,000 in its first four weeks.
