Marvel retains the top spot in this weekend’s box office, while one new release exceeds expectations.

Iron Man 3 takes the number 1 spot for the second weekend in a row with $72 million. Marvel’s first film of “Phase Two” is now up to $284 million in domestic grosses, and is the highest grossing film of 2013 (so far).

And, if you combine international numbers, Iron Man 3 has grossed $948 million worldwide, which is good enough for the number 21 spot on the all-time highest grossers list. Next up: $1 billion worldwide.

In at number 2 is The Great Gatsby (read our review) with $51 million. Heading into the weekend, most figured the period drama – based on F. Scott Fitzgerald’s beloved novel – would do well given the stars involved (Leonardo DiCaprio, Carey Mulligan, and Tobey Maguire), but few expected it would gross over $50 million.

The second weekend of May is typically hard on new releases, but that was not the case here. Warner Bros. is probably very pleased with their decision to delay the film from December into May.

Pain & Gain comes in at a distant 3 with $5 million. Michael Bay will be back with Transformers 4 next year to dominate the summer box office, but for now he’ll have to settle for a $41 million domestic gross over three weeks.

Tyler Perry Presents Peeples, which stars Craig Robinson (The Office) and Kerry Washington (Django Unchained), opens at number 4 with only $4.8 million. While Tyler Perry only produced the film, Peeples is the lowest opening weekend for a movie with the director’s name attached to it.

Rounding out the top 5 is 42 with $4.6 million. Warner Bros. should be extremely proud of the Jackie Robinson biopic, which is up to $84 million in domestic grosses.

Oblivion is the number 6 film this weekend with $3.8 million. Tom Cruise’s sci-fi blockbuster is now up to $81 million in domestic grosses, and $242 million worldwide.

The animated film The Croods comes in at number 7 with $3.6 million, which brings the film’s domestic total up to$173 million. Look for The Croods to become a staple of Dreamworks Animation’s slate if the proposed sequel can duplicate this first film’s success.

The Big Wedding takes the number 8 spot with $2.5 million and $18 million over three weeks. We can officially label this one a flop, as there is little chance it will make back its $35 million budget.

In at number 9 is Mud with $2.3 million. The Matthew McConaughey drama is up to $8 million in domestic grosses.

Oz the Great and Powerful rounds out the top 10 with $802,000, which brings its domestic total up to $229 million. As you can see, when a weekend is this front-loaded, it doesn’t take much to crack the top 10.

Outside the top 10: Star Trek Into Darkness opened with $31 million in select international territories, which is a 70% improvement over the first J.J. Abrams-directed Star Trek. The sequel opens in the U.S. on Friday.
