First Man won the Academy Award for Best Visual Effects at the 91st Academy Awards. The film received four nominations in total, including Best Sound Mixing, Best Sound Editing, and Best Production Design. The visual effects team of Paul Lambert, Ian Hunter, Tristan Myles, and J. D. Schwalm accepted the award.
First Man does not show Armstrong and Aldrin physically planting the American flag on the lunar surface. Director Damien Chazelle stated this was not a political decision, explaining that the flag is visible standing on the surface and that he chose to focus on lesser-known personal aspects of the mission. The omission drew public criticism from Senator Marco Rubio and President Donald Trump, and some analysts speculated it contributed to the film's below-expectations opening weekend.
Karen Armstrong was Neil Armstrong's two-year-old daughter who died of a brain tumor before his astronaut career began. Her loss is a recurring emotional thread throughout the film. In a fictional scene, Armstrong drops Karen's bracelet into Little West Crater on the lunar surface, though there is no historical record that he took the bracelet to the Moon.
