Forget “Batman v Superman.” The real battle in Hollywood is DC Comics vs. Marvel — and Disney’s Marvel right now has the upper hand.

Which makes Warner Bros.’ mission to use “Batman vs. Superman” to turn its DC Comics into a non-stop franchise powerhouse all the more important.

If the movie lays an egg at the box office, it could hurt DC Comics’ upcoming “Suicide Squad” (Aug. 5) and “Wonder Woman” (2017).

It could also put more heat on Warner Bros. production chief Greg Silverman, who’s under pressure to get his studio in gear after a string of disappointments.

Silverman has to be happy with some of the early results.

“Batman v Superman: Dawn of Justice,” pulled in $27.7 million at the box office Thursday night, putting it on track to become the movie with the best-ever March opening.

Weekend projections are for $160 million-to-$170 million, according to a Deadline.com report on Friday.

That could top the current March champ: 2012’s “The Dark Knight Rises,” which took in $160.8 million.

Globally, the latest DC movie is expected sell $300 million in tickets.

By comparison, Marvel’s “Avengers” took in $207 million on its opening weekend back in May 2012.

Since DC Comics’ “Dark Knight” in 2008, Warner Bros. has racked up $558.8 million in opening weekend box office ticket sales on seven movies, according to ComScore.

But Marvel has done better, ringing up $904.9 million in opening weekend box office on its last seven movies.

The two studios will duke it out this year. Before DC Comics’ “Suicide Squad” in August, Marvel will unspool “Captain America: Civil War” on May 6.

Silverman must also be happy that Wall Street expectations for “Batman v Superman” are so high that FBR analyst Barton Crockett raised his projections for cinema chains such as AMC.

Crockett is pencilling in a 9.1 percent bump in first-quarter box office revenue. Of course, the success of “Deadpool” and “Zootopia” helped that decision.

On the down side, Silverman has to be hoping that a slew of bad reviews for his latest film — starring Ben Affleck, Harry Cavill and Amy Adams — won’t scare away moviegoers.

The movie received a stinging 30 percent positive rating on Rotten Tomatoes, a movie review aggregator.

The New Yorker’s film critic, Anthony Lane, wonders if director Zack Snyder previously worked for food mixer brand Nutribullet since he “simply slings another ingredient into the mix,” reads his review. Lane also complains that the music “renders large portions of dialogue inaudible.”

Paul Dergarabedian, senior media analyst at ComScore, told The Post, “This movie is really important because it sets up ‘Justice League’ and ‘Suicide Squad.’ It’s similar to [the importance of] ‘The Force Awakens’ to the ‘Star Wars’ future.”

He notes that advance box office demand is high as is social conversation indicating a huge amount of interest. “What else are we going to see? It’s five weeks until ‘Captain America,’” said Dergarabedian. Late March, he points out, is hardly a hotbed of blockbusters, but things start to heat up once May starts and the studios roll out the big guns.
