There was never any doubt that Marvel's Captain America: Civil War would be a hit. But just how big a hit wasn't immediately clear. This monster blockbuster has pulled in $75.3 million during its first day in release. It is now estimated to have an opening weekend between $172 million and $178.8 million. If it can soar just a little higher than 2013's Iron Man 3, which earned a first weekend total of $174.1 million, it will be the 5th highest opening of all time. Anything lower will slide it into 6th place. That said, Civil War's Friday numbers fell short of Batman V Superman's opening day earnings of $81.5 million.

That doesn't mean it won't soar past the DC Comics adventure throughout the rest of the weekend, as the movie is garnering better word-of-mouth. As it stands now, Captain America: Civil War will give Disney five of the six top grossing domestic openings of all time. The pack is lead by 2015's Star Wars: The Force Awakens with $247.97 million, but the number two spot belongs to Universal's Jurassic World, which earned an amazing $208.8 million last summer. Marvel's The Avengers is in 3rd place with $207.4 million, and coming in 4th is Avengers: Age of Ultron with $191.2 million. Batman v Superman: Dawn of Justice is resting in the 7th best domestic opening slot with $166 million. And while that movie quickly dipped throughout its first weekend, Marvel's Civil War is only expected to rise.

$25 million of Captain America: Civil War's Friday gross of $75.3 million came from Thursday preview screenings. While some prognosticators pegged the Marvel Phase 3 adventure's opening weekend at a high $190 to $200 million, Disney never wavered from their own predicted estimates of around $175 million. And most insiders don't believe that Captain America 3 is falling short, with summer 2016 off to a great start. Though, Deadline notes that now there is some added pressure in making sure Avengers: Infinity War Part 1 and Part 2 are significantly special to keep the core audience coming back.

As it stands, Captain America: Civil War is one of the best reviewed Marvel movies yet, and is a hit with both fans and critics. Though it will likely fall short of the original Avengers and Age of Ultron, it does hold the highest opening for any of the three Captain America standalone movies. Captain America: The First Avenger, released in 2011, only earned $25 million on its first Friday for a weekend total of $65 million. Winter Soldier came in with an opening day tally of $36 million for a first weekend gross of $95 million. Civil War matched Age of Ultron's budget of $250 million. The movie has already proven to be profitable with a worldwide cume of $366.4 thus far. It's expected that number will rise to $600 million by the time the weekend is over.

Captain America 3 currently has an A CinemaScore and is rated fresh on Rotten Tomatoes with 91% positive reviews. Unlike Batman V Superman, Civil War is not expected to have such huge drop-offs in the coming weeks. Many expect it will hold steady throughout its second weekend, taking the top spot again as it goes against the thriller Money Monster starring George Clooney and Julia Roberts, and the horror movie The Darkness headlined by Kevin Bacon.

It should also fare quite well in its third weekend, as Angry Birds flies in along with the Seth Rogen and Zac Efron sequel Neighbors 2: Sorority Rising. Also opening in Civil War's third week is The Nice Guys, a comedy that pairs Russell Crowe and Ryan Gosling. It arrives from Iron Man 3 director Shane Black. Captain America will face its stiffest competition over Memorial Day weekend, as it is pitted against Disney's own sequel Alice Through the Looking Glass and the second big Marvel movie of the summer X-Men: Apocalypse, which comes from 20th Century Fox Studios. Stay tuned throughout the weekend as we bring you the total opening grosses for Captain America: Civil War.
