Andy Weir, who wrote The Martian and Project Hail Mary, just shared his surprisingly simple approach to writing bestselling novels. The author behind two major Hollywood adaptations revealed tips that any writer can use.
Weir’s success speaks for itself. The Martian became a Ridley Scott movie starring Matt Damon that made over $600 million worldwide. His latest book, Project Hail Mary, just had a massive opening weekend and looks set to become another blockbuster adaptation.
Write Like You’re Explaining to a Friend
Weir’s main advice? Keep it simple. He writes his complex science fiction stories the same way he’d explain them to someone at a coffee shop. No fancy words, no showing off. Just clear, engaging storytelling that pulls readers in.
The author is known for making complicated science feel accessible. In The Martian, he made rocket science and botany interesting enough that millions of people couldn’t put the book down. His secret isn’t dumbing things down – it’s making smart content that anyone can follow.
Weir also emphasized writing what you genuinely find interesting. Both his novels started as passion projects where he explored topics he was curious about. That genuine enthusiasm shows up on every page.
What’s Next
With Project Hail Mary’s strong performance, Hollywood is already circling for the film rights. Weir’s approach proves that simple, clear writing can create stories that work across books, movies, and massive audiences.
