Production for "Avengers: Infinity War" is currently in high gear, with filming scheduled in various locations including Scotland. As filming ensues, directors Anthony and Joe Russo have begun teasing new material for the heavily anticipated superhero movie.

On Twitter, the Russo Brothers shared a mysterious image, which many theorize is a part of the vault where Thanos keeps the Infinity Gauntlet, as seen in the mid-credits scene in "Avengers: Age of Ultron."

According to ComicBookMovie, Marvel Studios president Kevin Feige has confirmed that the Infinity Gauntlet is not confined in Odin's vault. It is likely that the audience will be seeing more of Thanos' vault in "Infinity War" as Thanos keeps returning to it as he assembles the Infinity Stones on the Gauntlet one by one.

Meanwhile, "Avengers: Infinity War" is poised to become the most expensive film ever made in movie history, potentially beating current title holder "Pirates of the Caribbean: On Stanger Tides."

According to The Independent, "Avengers: Infinity War" and another still-unnamed "Avengers" film reportedly has a budget of $1 billion. The assumption was made after Pinewood Atlanta Studios co-owner Dan Cathy mentioned during the African American Film Critics Association that the staggering amount is being used for a certain film, without dropping any names.

The "Avengers" films appears to be the best guess, considering that "Infinity War" is also filming in Atlanta, and has rented out the facility for filming schedules next year.

Moreover, the numbers line up with previous reports that Robert Downey Jr. is receiving $200 million for reprising his role as Iron Man/Tony Stark in the next two "Avengers" movies. Approximately $400 million of the budget is said to have been spent on the salaries for principal actors, screenwriters, directors and producers.

"Pirates of the Caribbean: On Stranger Tides" currently holds the record for having the biggest budget of all time. The Disney film reportedly cost $397 million to make. Even if the $1 billion budget will be split between two "Avengers" films, the amount still puts the budget for both films at least $500 million each.
