2017 Preview: June

June 1st, 2017

Despicable Me 3

May was a really soft month with only one unqualified hit, Guardians of the Galaxy, Vol. 2, which is climbing towards $375 million domestically. The second biggest hit of the month will be Pirates of the Caribbean: Dead Men Tell No Tales and I would be surprised if it tops $150 million by any serious margin. June looks a lot more profitable. There are five weeks and every week there is at least one film with a great shot at $100 million or more. In fact, there are four films with at least a decent shot at $200 million and we could double the number of $300 million hits released so far this year. Wonder Woman is widely expected to start the month with an explosive debut and pulling in more than $100 million during its opening weekend is more and more likely. That said, Despicable Me 3 will probably end up being the biggest hit overall with over $300 million. Meanwhile, Cars 3 and Transformers: The Last Knight are both aiming for $200 million. Last June was not particularly strong, outside of one hit. Finding Dory earned nearly $500 million domestically, while the second best film, Central Intelligence, barely earned a quarter of that. I don’t think any film will come close to Finding Dory, but there’s a lot more depth this time around and I have high hopes 2017 will extend its lead. More...

2016 Preview: July

July 1st, 2016

The Secret Life of Pets

It's July 1st, which is Canada Day. To celebrate, I wanted to give a gift to my American readers down south, so here's a bunch of "u"s. U, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u. Now you can spell words like "colour" and "neighbour" correctly. As for the July preview... June wasn't a good month, despite Finding Dory being on pace to become the biggest hit of the year so far. Most other films failed to match expectations and as a result, 2016's lead over 2015 has nearly evaporated. In fact, ticket sales are below last year's pace. So how does July look in comparison? Well, last July, there were five films that earned more than $100 million, led by Minions, which earned more than $300 million. This July, there are five films that should earn more than $100 million, led by The Secret Life of Pets, which should earned around $250 million. I don't think July 2016 will live up to July 2015, but it should be close. Maybe if one of the expected midlevel hits is a surprise $100 million hit, or if two more of the $100 million hits crack $200 million, then the month will look great. Or one of the expected $100 million hits could flop and 2016 will actually fall behind 2015, even without taking into account ticket price inflation. More...

2016 Preview: May

May 1st, 2016

Captain America: Civil War

April started on a soft note and ended weak, but thanks to The Jungle Book, overall the month was actually really good. That's what happens when you get a surprise $300 million hit. This bodes well for May, which is both a slow month and a fantastic month. There are only four weekends and only eight movies coming out, but of those eight films, five have a shot at $100 million. The potential blockbusters are led by Captain America: Civil War, which is not only going to be the biggest hit of the month, but according to a Fandango survey, it is the most anticipated film of the summer. (On a side note, Finding Dory is the most anticipated family film of the summer and Ghostbusters is the most anticipated comedy of the summer. I was surprised by the last result.) Both Alice Through the Looking Glass and X-Men: Apocalypse have real shots at $200 million. One of them could get to $300 million, if they weren't opening against each other. Overall, the month looks excellent. Even better, last May there was only one monster hit, The Avengers: Age of Ultron, and most analysts think Captain America: Civil War will beat it at the box office. (There's also the issue of the misalignment in the weekends, which hurt April, but will really help May.) More...

2014 Preview: May

May 1st, 2014

The Amazing Spider-Man 2 poster

It has been a great year so far and April was again a strong month. The box office was led by Captain America: The Winter Soldier, as it became the second film of the year to reach $200 million, while Rio 2 is on pace to become the seventh $100 million hit of the year. Big picture, 2014 has already hit $3 billion, which isn't a record for this time of the year, but it is $250 million ahead of 2013. That streak ends in May. Don't get me wrong. There are six films opening this month that at least have a shot at $100 million and two of those should earn more than $200 million and there are two others that at least have a shot at that milestone. Leading the way is The Amazing Spider-Man 2, which is looking to top The Winter Soldier and become the second biggest hit of the year so far. Its main competition this month is X-men: Days of Future Past, while Godzilla also has a shot at $200 million. Unfortunately, this month last year, Iron Man 3 earned more than $400 million, while two other films took in $200 million and seven films in total reached the century mark. That is going to be really hard to replicate this year and 2014 will likely lose some of its lead over 2013. Fortunately, 2014 has such a big lead that unless the box office really slumps, it will end the month with at least a small lead over 2013. More...
