Avengers: Infinity War could be the most expensive film ever made

As anyone who has been to the cinema recently will tell you, superhero films are so hot right now.

Today, Logan finally reaches cinemas. Next up is Guardians of the Galaxy Vol. 2. Then Spider-Man: Homecoming. Oh, and Wonder Women. Then Thor: Ragnarok. And Justice League somewhere in there.

It should come as no surprise that these films have an incredibly high budget, often around the $200 million mark.

However, the upcoming Avengers films - Infinity War and another as-yet-untitled fourth film - will reportedly have an unprecedented budget of $1 billion.

Films to get excited about in 2017
Speaking at a recent African American Film Critics Association meeting, Pinewood Atlanta Studios co-owner Dan Cathy mentioned the staggering number without naming which film he was referencing.

Considering Disney are currently filming Infinity War in Atlanta and has rented the facility for the next year, we can safely assume the studio owner is talking about the Avengers flick.

The number falls in line with previous reports that claimed Robert Downey Jr will be paid $200 million to appear as Iron Man in both films. Around $400 million of the budget is thought to have been spent on principle actors, screenwriters, directors, and producers.

Currently, the highest budget film of all time is Pirates of the Caribbean: On Stranger Tides, which cost a reported $397 million to makes. If the $1 billion budget is true, that makes both parts $500 million each, and posits them as the highest budget films of all time.
