Then came Matt Damon as a charmingly goofy botanist in 2015's The Martian, adapted from Weir's award-winning novel. Director Ridley Scott and screenwriter Drew Goddard turned a novel about growing potatoes and doing calculations into a crowd-pleasing comedy that even impressed critics. Now, Weir's work is back on the big screen with Project Hail Mary, which once more has Goddard penning the adapted screenplay.
