It's hardly a surprise that the second film in the Marvel franchise would rule the box office. It's mid-May, which in Hollywood means the start of summer movies and the return of sequels to American movie theaters.
The number of sequels coming out peaks in the summer when kids are out of school and the heat and the humidity drive people to find comfort in air-conditioned theaters. Among movies with budgets of more than $10 million, 48 percent of sequels released since 2001 came out between May and August, according to data from OpusData, a database of movie financial information.
"The studios will say for their summer plan, 'We've got to have the next big franchise,'" said Bruce Nash, founder of Nash Information Services, which runs OpusData. "Then they might have one or two less expensive films that they're hoping are the next franchises for next year."
