Their film evolved from a heterosexual love story to a blossoming romance between a man and a male corpse.

‘Swiss Army Man’ is a film about a man named Hank (Paul Dano) stuck on a stranded island. Right as he is about to commit suicide, a dead body (played by Daniel Radcliffe) washes up on the shore and Hank uses and develops a friendship with the corpse.

“We just kept rewriting and rewriting, until we allowed them to fall in love. And once we allowed ourselves to write that, that story really started to grow and blossom into something worthwhile,” Daniel Kwan told the Telegraph in an interview with co-writer Daniel Scheinert. Originally, an opposite-sex love was at the forefront.

“In some ways, we thought we were making a more conventional guy trying to get back to his girl story. But the more drafts we wrote, the more we realised,” Kwan said. “That was a really interesting turning point – when we let Hank and Manny fall in love and accidentally made a gay necrophilia movie.”

‘Swiss Army Man’ released in theatres on June 24 and has 3.5 stars on IMDB.
