"Rock of Ages" is looking at disappointing a debut of $14 million to $16 million; R-rated comedy "That's My Boy" might only get to $13 million in a major blow for Adam Sandler.

The soft performances of Adam Shankman's musical Rock of Ages -- with an all-star cast including Tom Cruise, Alec Baldwin and Russell Brand -- and Adam Sandler's R-rated comedy That's My Boy are major disappointments for their respective studios and stars, particularly Sandler.

Madagascar 3 earned $10 million on Friday, bringing its eight-day North American cume to roughly $95 million. The threequel, from DreamWorks Animation and Paramount, is expected to earn $33 million to $36 million for the weekend.

From 20th Century Fox, Prometheus grossed $5.8 million on Friday for a cume of $74.4 million and projected Father's Day weekend take of $20 million to $21 million.

Even though Prometheus fell 72 percent on its second Friday, it still came in ahead of New Line and Warner Bros.' jukebox musical Rock of Ages, which grossed $5.4 million.

Rock of Ages, based on the hit Broadway musical, is now expected to only gross $14 million to $16 million for the weekend if it doesn't get a big bump, well behind the openings of Shankman's musical Hairspray and Universal's Mamma Mia! Both of those films opened just north of $25 million.

Rock of Ages earned a so-so B CinemaScore; That's My Boy got a B-.

From Sony -- Sandler's longtime home studio -- That's My Boy grossed $4.6 million on Friday for a projected weekend in the $12 million to $13 million range. That would represent Sandler's lowest opening for a comedy since Spanglish in 2004 ($8.8 million).

That's My Boy, pairing Sandler with Andy Samberg, is the actor's first R-rated comedy since Funny People, which opened to $22.7 million in July 2007.

There's a chance that Universal holdover Snow White and the Huntsman could beat That's My Boy for No. 4.

Snow White grossed $4 million on Friday, with Universal projecting a $13 million weekend.
