Marvel's Blade Couldn't Sleep over Surprise MCU Cameo

MCU Blade actor Mahershala Ali acknowledged to losing sleep over his vocal role in the post-credits scene of Marvel Studios Eternals during an interview on The Late Show with Stephen Colbert.

“You lose a lot of sleep over it. Like, I was losing a lot of sleep over this line, because ideally, you want to be talking once you are filming. 100% of the time, my first day on any set, on any job, I hate it, I hate how I sound. I don’t believe myself. You’re trying to get comfortable in the character, so to have to talk before you’re even actually filming was challenging. But I’m grateful for it, because it made it feel real, it’s like ‘OK, now we’re going.’”
