When the trailer for Chadwick Boseman's upcoming Marvel epic Black Pantherdropped earlier this month, it racked up millions of views in the first 24 hours and set the internet on fire with fans freaking out about how great the movie looks.
According to Boseman, he felt that same level of awe and excitement while watching the action-packed preview, despite being the star.

"When I was watching it, it was like I forgot I was in the movie," the 40-year-old star told Jimmy Kimmel on Wednesday. "It was so exciting, I literally, for like three minutes, just stared at the screen."
The trailer, which first aired during Game 4 of the NBA Finals between the Golden State Warriors and the Cleveland Cavaliers, was originally supposed to air during Game 5 -- and Boseman said the timing of the release actually forced him to reconsider which team he supported.
"I heard it was gonna be on during Game 5, so I was rooting for Golden State," he recounted. "But when they were just running through the Cavs I started rooting for the Cavs, just so they could get to Game 5!"

While he's basking in the glory of Black Panther, Boseman is also starring in the upcoming biopic Marshall, in which he stars as a young Thurgood Marshall, the first African-American Supreme Court Justice.
"It's a biopic in some ways, but it's really not," Boseman said. "What it is, is a whodunit. It's a thriller. If you didn't know anything about Thurgood Marshall, you could watch this movie and enjoy it as a courtroom drama."

The story reportedly details one of Marshall's early cases as an attorney, which went on to define his career.
This is the third biopic Boseman has starred in following his portrayals of Jackie Robinson in 2013's 42 and James Brown in 2014's Get on Up.
"I had said I didn't want to do anymore movies about real people, but the script was really good," Boseman shared.
The star explained that, whether he's playing a real-life person or a fictitious character, "Acting is the same regardless. But you're responsible for certain things when you play a real person."

"Each movie you do about a real person is like a painting, and you choose certain things in the painting that you want to pull out and you want to show," he added. "So for this one, it was the spirit of the man. He lives hard. He works hard. He fights hard. So I wanted to show this person who was just an interesting person."
Marshall is due to hit screens Oct. 13, while Black Panther claws its way into theaters Feb. 16, 2018.
