2nd UPDATE: Warner Bros. just reported Easter Monday numbers for Batman v Superman. A number of countries were on holiday yesterday. Together with $15M domestic, overseas raked in $31M on Monday, sending the day’s global total to $46M. Worldwide, BvS stands at $468.6M. WB has revised its weekend opening to $256.5m internationally putting worldwide at $422.6m. In the global opening record books, BvS is the fourth highest behind Star Wars: The Force Awakens ($529M), Jurassic World ($524.9M), and Harry Potter and the Deathly Hallows Part 2 ($483.2M). Sources are keen for me to point out that those titles that BvS outflanks on the list; many of them had unique foreign rollouts, and unlike BvS didn’t have China during their first frames. JW, BvS and Spider-Man 3 included China in their day and date debuts. More details on foreign coming soon…

With two indie movies going wide this weekend at the domestic B.O. –PureFlix’s God’s Not Dead 2 at 2,318 venues and Freestyle’s Meet the Blacks at 1,000 theaters– there’s some murmuring that BvS’ drop might not be as steep as we originally thought ( -65%). Word of mouth seems to be more upbeat than the CinemaScore and reviews.

1st UPDATE, 7:14AM: With 45% of schools off yesterday, per ComScore, it was like another holiday for Warner Bros’ Batman V Superman: Dawn of Justice, which racked up the best Monday in March with $15.05 million, a 55% drop from Sunday’s $33.79M. That number outstrips the previous Monday high ($10.8M) posted by Lionsgate’s The Hunger Games on March 26, 2012.

Through four days, BvS counts $181.06M at the domestic box office after hitting opening-weekend records for Easter, March, pre-summer as well as Ben Affleck, Henry Cavill and director Zack Snyder. That four-day run ranks eighth behind The Dark Knight‘s $182.9M and ahead of The Dark Knight Rises‘ $180.3M. BvS is not the top Monday before the summer season starts; that belongs to 20th Century Fox’s Deadpool, which made $19.76M on February 15, the 10th-best second day of the week of all time.

This weekend, industry estimates expect BvS to drop 65% or $58.1M, a bit steeper than most blockbusters considering its batch of poor reviews at 29% Rotten and B CinemaScore. Few blockbusters opening north of $100M put up those types of numbers (usually big openers receive A CinemaScores and fresh Rotten scores); two films to which BvS comes close are The Twilight Saga: Breaking Dawn 2 ($138.1M opening, B+ CinemaScore, 24% Rotten) and Transformers: Revenge of the Fallen ($109M opening, B+ CinemaScore, 19% Rotten). Financial analysts and packagers believe BvS definitely will profit in the long run after all ancillary revenues are counted.

As superhero films crowd headlines, 20th Century Fox’s Deadpool will become the second-highest grossing R-rated film at the box office with $350.7M today, taking over Warner Bros.’ American Sniper ($350.1M). 2004’s Mel Gibson biblical epic The Passion of the Christ continues to hold the top spot with $370.8M.

Disney’s Zootopia took second yesterday with an estimated $4.77M, taking its cume in its fourth week to $246.2M, while Gold Circle/Playtone/HBO’s My Big Fat Greek Wedding 2 from Universal slotted third with $2.04M and a four-day cume of $19.9M.
