Sean Penn’s Unusual Method: Why He Told Cast to Dislike Michael J Fox
Sean Penn’s approach on the set of Casualties of War saw him urging fellow actors to dislike Michael J Fox’s character, as revealed by Stephen Baldwin. Despite this, Fox still looks back fondly on the film.
It’s hard to find anyone who doesn’t have a soft spot for Michael J Fox. Even after being diagnosed with Parkinson’s at just 30, he’s stayed upbeat and become a beacon of hope for many, not just those living with the illness. His foundation has raised a fortune for research, and he’s still remembered fondly for his roles—Marty McFly being the standout. If there’s anyone who might have a bone to pick with him, it’d probably be Eric Stolz, who lost out on Back to the Future, or, surprisingly, Sean Penn.
The story comes from Stephen Baldwin, who shared his experience on the One Bad Movie podcast while chatting about the 1989 Brian De Palma film, Casualties of War. Baldwin, who had a minor part in the film, recalled a chat with Penn that took a strange turn.
‘We can’t be friends with Mike Fox,’
Penn told him. When Baldwin asked why, Penn explained it was all about the story.
‘Our characters, we hate him. So you have to hate him with me. Do what I tell you.’
Method Acting on Set
Casualties of War centres on the notorious ‘Hill 192’ incident during the Vietnam War, where a group of American soldiers kidnap a Vietnamese woman, leading to horrific consequences. Fox plays the only one in the group who objects, and the story unfolds through his memories. Penn is the sergeant who, after losing a mate, orders the abduction. Baldwin was originally cast in a bigger role but was let go a few days in, replaced by John C Reilly. His brief time on set was enough to witness Penn’s intense approach.
Penn’s comments weren’t personal, but rather part of his commitment to method acting—a technique he’s known for. Even back in his Fast Times at Ridgemont High days, he’d stay in character and wouldn’t answer to his real name. Supporters of this style reckon it brings out the best performances, but it’s not everyone’s cup of tea. Whether it was necessary for Penn to push others to join in is up for debate, especially given the sensitive subject matter.
Fox’s Perspective
Despite the on-set tension, Fox has nothing but good things to say about Casualties of War. He’s called it his most underrated film and seems unfazed by the fact that his co-stars were told to keep their distance. For him, the experience remains a highlight, regardless of the method acting antics happening around him.
