LOS ANGELES — “Guardians of the Galaxy” continues to rule the box office universe.

The cosmic Marvel adventure arrived in first place at the box office for a fourth weekend, according to studio estimates Sunday. The domestic haul for “Guardians,” which features Chris Pratt and Zoe Saldana as intergalactic do-gooders, now stands at $294.6 million after six weeks of release.

“Guardians” further cemented itself as the top grossing film of the year in North America, eclipsing the $259.8 million earned by fellow Marvel movie “Captain America: The Winter Soldier.” The sci-fi romp earned an additional $11.5 million internationally, bringing its worldwide total to $586.2 million.

Despite the continued success of “Guardians,” the weekend box office marked the slowest of the year with the total for all films released projected at $65 million, down 23 percent from a year ago.

The only new film, the musical drama “The Identical,” dismally debuted in 11th place at $1.9 million. Estimated weekend sales:
