Batman v Superman: Dawn of Justice managed to defend its box office crown last weekend by taking in $51.3 million, although it suffered a massive drop of 69.1% from its record-breaking debut of $166 million. That second-frame decrease was amongst the biggest ever for any superhero movie. And while it will surely suffer another big drop this weekend, it should still make enough to take down three newcomers, Universal's The Boss, STX Entertainment's Hardcore Henry and Relativity's Before I Wake. However, this may likely be the last weekend Batman v Superman: Dawn of Justice remains on top.

We're guessing that Batman v Superman: Dawn of Justice suffers another big drop of 60%, which would put its third weekend tally at $20.5 million. As for the newcomers, Pro.BoxOffice.com projects that The Boss will earn $17.5 million, which should be good for second place, followed by holdover Zootopia in third place with $14.4 million and Hardcore Henry and Before I Wake rounding out the top 5 with $10.5 million and $9 million respectively. Unlike Batman v Superman: Dawn of Justice, Zootopia keeps posting minimal decreases, dropping just 19.6% last weekend.

Batman v Superman: Dawn of Justice managed to surpass most expectations during its debut, taking in $166 million domestically and $424 million worldwide, the best global debut for any superhero movie in history. Still, Batman v Superman: Dawn of Justice didn't fare well with critics. The superhero movie currently has a 29% rating on Rotten Tomatoes but the audience score is still overwhelmingly positive, with 70% of the RT users favoring the movie. Batman v Superman: Dawn of Justice has currently made $260.4 million domestically and $442.5 million internationally for a global tally of $682.9 million from a $250 million budget.

Academy Award-nominated star Melissa McCarthy headlines The Boss as a titan of industry who is sent to prison after she's caught for insider trading.  When she emerges ready to rebrand herself as America's latest sweetheart, not everyone she screwed over is so quick to forgive and forget. McCarthy is joined in The Boss by an all-star cast led by Kristen Bell, Peter Dinklage and Kathy Bates.  Directed by Ben Falcone, the comedy is based on an original character created by McCarthy and written by McCarthy and Falcone alongside their Groundlings collaborator, Steve Mallory. The film is produced by McCarthy and Falcone through their On the Day productions and Will Ferrell, Adam McKay and Chris Henchy through their Gary Sanchez Productions.

In the intense and heart pounding supernatural thriller Before I Wake, Jessie (Kate Bosworth) and Mark (Thomas Jane) decide to take in a sweet and loving 8-year-old boy, Cody. Unbeknownst to them, Cody is terrified of falling asleep. At first, they assume his previous unstable homes caused his aversion to sleep, but soon discover why: Cody's dreams manifest in reality as he sleeps. In one moment they experience the incredible wonder of Cody's imagination, and in the next, the horrific nature of his night terrors. To save their new family, Jessie and Mark embark on a dangerous hunt to uncover the truth behind Cody's nightmares.

Hardcore Henry centers on the title character, a newly resurrected cyborg who must save his wife/creator from the clutches of a psychotic tyrant with telekinetic powers, AKAN, and his army of mercenaries. Fighting alongside Henry is Jimmy, who is Henry's only hope to make it through the day. Hardcore Henry takes place over the course of one day, in Moscow, Russia, with a cast that includes Sharlto Copley, Danila Kozlovskiy, Haley Bennett and Tim Roth. Hardcore Henry is currently at 81% on Rotten Tomatoes, but none of the other newcomers have RT scores just yet.

The top 10 will be rounded out by My Big Fat Greek Wedding 2 ($6.1 million), God's Not Dead 2 ($4.5 million), Miracles from Heaven ($3.9 million), The Divergent Series: Allegiant ($3.1 million) and 10 Cloverfield Lane $2.8 million. Also debuting in limited release is Fox Searchlight's Demolition, Drafthouse Films' The Invitation, The Orchard's Louder Than Bombs, Focus World's Mr. Right, and Starz Media's One More Time. Demolition is arriving in 550 theaters this weekend, so it's possible that it could sneak into the top 10 if it performs well in limited release, but we'll have to wait and see.

Looking forward to next weekend, three new movies are slated to debut in wide release, Disney's highly-anticipated adaptation of Rudyard Kipling's The Jungle Book, Warner Bros.' comedy sequel Barbershop: The Next Cut and Lionsgate's Criminal. Also opening in limited release is A24's new thriller Green Room, The Weinstein Company's musical Sing Street, Screen Media's Rio, I Love You, Yash Raj's Fan and Screen Media's Colonia.
