Avengers: Endgame is right around the corner, but Marvel's biggest fans are avoiding any and all news about the film. With Endgame's theatrical release upon us, MCU adherents are trying to avoid the spoilers that are circulating around the Internet.

The film's directors, the Russo Brothers, sympathized with spoiler-avoiding fans, urging others to not spoil the film for those who haven't seen it yet.

But if fans counted on the film's veteran cast to not let any secrets slip, they may have been disappointed by a recent guest appearance by the Endgame stars on The Late Show with Stephen Colbert.

During the segment "Just One Question," Chris Evans, Scarlett Johansson, Brie Larson, Chris Hemsworth, Jeremy Renner, Mark Ruffalo and Don Cheadle were asked a variety of random questions about their characters.

For the most part, the cast had comedic answers for each question and avoided revealing spoilers.

However, early into the segment, Evans appears to drop a major spoiler. When asked who was the Avengers' biggest enemy, the Captain America actor responded, "Chafing. If you've ever run through an interdimensional portal, you know what I mean."

Obviously the chafing part was a joke and the biggest enemy is--as his cast mates said--Thanos. But, "running through an interdeminsional portal" possibly confirms the popular theory that the film's heroes will travel to the Quantum Realm to avenge the fallen and restore the lives lost at the snapping fingers of the Mad Titan.

We'll see if this spoiler reveals to be true when Avengers: Endgame hits theaters on April 26.
