In what’s become a summer tradition, movies released between now and the beginning of September are predominantly sequels or based on comic books or other popular characters.

It’s all an effort to create buzz and draw moviegoers to theaters. Because box office numbers are down this year, every movie studio is trying to hedge its bets.

Smaller films have to pick just the right day or go against the blockbusters. “Jumping the Broom,” the family-friendly story of two very different families coming together for a wedding, will face off against “Thor” this weekend on purpose.

“We are opening on Mother’s Day weekend because our research shows us this is the kind of movie sons will want to take their mothers to see,” says Tracey Edmonds, “Jumping the Broom” producer.

Those two films go head-to-head at the start of the blockbuster season. Here’s a look at some of the movies coming this summer. (Note: Release dates are subject to change.)
