"How to Train Your Dragon 2" and "22 Jump Street" will compete for the number one spot at the box office this weekend.

DreamWorks returns to the marketplace after a number of months away from the box office. This time the studio returns with "How to Train Your Dragon 2." The movie will open in 4,253 theaters and is expected to make an estimated $55 million. That would be a far better opening than the 2010 original film, which opened with $43 million and ended up making $217 million. The question DreamWorks has to worry about is whether this new sequel will actually surpass the original's gross given the lackluster box office franchise films have had over the first month of the summer. "How to Train Your Dragon 2," however, has two advantages from the other action films. The movie is the first children-oriented film of the summer and it also has outstanding reviews. It currently has a 93 aggregate score on Rotten Tomatoes and with no real competition in the coming weekends, the movie could benefit from word of mouth.

Sony's "22 Jump Street" is also likely to open in the $50 million range. The movie, which is bowing in 3,306 theaters, is likely to benefit from the outstanding reviews and the following that the original 2012 film had. The original "21 Jump Street" made $36 million on its opening weekend and ended its run with $138 million. Sony should have no problem repeating the success of the original but it should also not expect the number one spot, especially with families flocking to see "How to Train Your Dragon 2;" the fact that the movie is rated R may also hurt its chances. However, given the lack of comedies, the Channing Tatum and Jonah Hill buddy action comedy is likely to succeed throughout the upcoming weeks.

Fox's "The Fault in Our Stars" is likely to take a big hit and make another $20 million. While that would be a 60 percent drop, the movie has already made $66 million and that should easily bring its gross to $86 million. Having cost only $12 million to make, it is already one of the surprise hits of the summer and is likely to end its run with a gross of $120 million.

The Angelina Jolie starrer "Maleficent" is likely to bring yet another $16 million. The fantasy has already racked an estimated $144 million and is still behind "Oz: The Great and Powerful." Nevertheless, it should end the weekend with $160 million and is still on track to make $200 million.

Meanwhile, the Tom Cruise actioner "Edge of Tomorrow" will continue to struggle. The film has only made $40 million in its first weekend and is likely to only bring in another $15 million this upcoming frame. That would bring its total to $55 million, which is a very poor gross for a movie that cost $178 million.    

"X-Men: Days of Future Past" is likely to make another $7 million this weekend which will bring its gross to over $200 million. The movie, which received rave reviews, is unlikely to pass "X-Men: The Last Stand" but at least it will become the third movie of the year to break the $200 million mark; it also becomes the third X-Men film to reach the $200 million mark domestically.

"A Million Ways to Die in The West" will bring in another $3 million, which will take its unsatisfactory gross to 36 million.

In art house theaters, a number of films will open in hopes of conquering the box office. The biggest film of the week is undoubtedly A24's "The Rover." The movie has garnered great reviews and is likely to bring Robert Pattinson fans to theaters. A24 will open the movie in New York and Los Angeles and will expand the feature next weekend.

Focus Features will bring "The Signal" into 120 theaters. The movie has garnered terrible reviews and has not really obtained enough buzz. The fact that Focus is throwing the movie into that many markets at a time means the company has no expectations and does not plan on expanding the picture in the upcoming weeks. "The Signal" is likely to become the fourth flop of the year for the distributor following "Walk of Shame," "Bad Words," and "That Awkward Moment."

Other releases will include IFC Film's "Hellion" starring Aaron Paul and Corinth Film's Israeli title "Policeman" starring "The Voice Israel" host Michael Aloni.

The Mexican feature "Heli," which won the Best Director award at Cannes, will be released in New York while Arc Entertainment will release the star-studded cancer drama "Lullaby." That movie stars Richard Jenkins, Amy Adams, Garrett Hedlund, Terrence Howard and Jennifer Hudson.

Music Box Films will also release "A Coffee in Berlin" to great reviews while Roadside Attractions will expand "Words and Pictures" in 119 theaters and bring its theater count to 217.
