The blockbuster recently passed Avatar to become the biggest movie ever at the global box office but the Oscar-nominated actress is in no rush to watch the Marvel production - because it's too long.
"It's three hours long, right? I haven't seen it," she tells EW Live.
Bassett, who initially joined the Marvel universe as Ramonda in "Black Panther" and has a small role in "Avengers: Endgame", plans to finally watch the star-studded superhero hit when she has substantial downtime.
"It is going to be on the plane," she added. "Oh, my God, carve out three hours?"
But her 13-year-old twins have seen the film - and they are fans: "They've seen it twice. I'm like, 'Y'all have fun. I'm just gonna relax and chill at home, thanks. Tell me all about it.' "
