**WARNING: THIS STORY CONTAINS SPOILERS FOR BLACK PANTHER**

— the year’s second highest-grossing movie. But director Ryan Coogler did have a small tinge of sadness as he was getting ready to release the superhero epic earlier this year. It’s hard to have regrets when you’re the filmmaker behind Black Panther the year’s second highest-grossing movie. But director Ryan Coogler did have a small tinge of sadness as he was getting ready to release the superhero epic earlier this year.

He was upset by his decision to kill off Ulysses Klaw, a Marvel supervillain that dates back to the 1960s.

In the film, which is available now on Blu-ray and digital, Klaw (played by Andy Serkis) is shockingly killed by Michael B. Jordan’s Erik Killmonger.

“I like Klaw,” Coogler said during an interview for Black Panther. “I was bugged by having to do that. It’s tough when you have to kill characters off and I really did love that character.”

Klaw played a small, but pivotal role in 2015’s Avengers: Age of Ultron, when he sold vibranium to the villainous Ultron. The character returned in Black Panther in another crucial role.

“I love Andy, he’s a lovely person,” Coogler says. “But again, it’s one of those things where when you’ve got so many people in a movie, some of them have to go. Klaw in this movie, he’s just having a good time. Every scene he’s in, he’s walking in like it’s the best day of his life. He’s got a swagger to him that’s interesting and for me it was cool to see Andy act like that. It was a real pleasure.”

The home video release of Black Panther includes bonus scenes and a commentary track that sheds light on Killmonger’s tragic backstory (in addition to his father being killed in the film’s opening scene, Coogler reveals that his mother died in prison).

Black Panther, which stars Chadwick Boseman, became one of the year’s most acclaimed films and grossed more than $1.3 billion worldwide. But just before its release, Coogler was ecstatic about getting a chance to direct his first comic book movie.

“I was a kid in the ’90s so I was a prime target for that stuff,” he said. “I love comic book movies. I love the genre. I loved the old Batman movies, the Tim Burton ones, I even dug the ones that came after them. I still got the Riddler cup and the Two-Face cup from Batman Forever. I loved the soundtrack, I bought the toys. So getting the opportunity to do one of these types of movies is just a blessing … This film felt so special to me.”
