How to Train Your Dragon 2” is leading “22 Jump Street” in pre-sales as the two sequels barrel toward what is shaping up to be a fiercely competitive weekend at the box office.

The DreamWorks Animation film about a Viking and his fire-breathing pal is the top-selling film on both Fandango and MovieTickets.com.

Fandango reports that “How to Train Your Dragon 2” is currently outselling “Rio 2,” “The Croods” and “Hotel Transylvania” at similar points in their sales cycle.

The animated sequel accounted for 20% of all tickets sold on MovieTickets.com on Wednesday, while “22 Jump Street” comprised 18% of all tickets sold.

“22 Jump Street,” which sees Jonah Hill and Channing Tatum’s undercover cops matriculate to college, is in second place on Fandango’s sales charts heading into the weekend. The R-rated comedy is outselling previous adult-oriented comedies “Ted” and “Neighbors.”

Both “How to Train Your Dragon 2” and “22 Jump Street” are expected to top $50 million this weekend. More bullish estimates put them in the $60 million range.

Fandango surveyed more than 1,000 ticket-buyers about their reasons for checking out “How to Train Your Dragon 2,” and found that 85% were eager to see a family-friendly film this summer. The picture seems likely to benefit from a lack of animated offerings at the multiplex in recent months, making it one of the only options for moviegoers with kids.
