Summary
The 2024 romantic-comedy movieSpace Cadetfollows Emma Roberts as an unconventional hopeful astronaut with a hilarious supporting cast. The original Prime Video movie takes an interesting approach tothe space moviesubgenre through Roberts’ character and the rest of the astronaut candidates, comically referred to as “Ascans.” WhileSpace Cadetis certainly a comedy with romantic elements, it has an important message and a lot of heart behind it.Space Cadetcan make viewers laugh out loud and tear up in its nearly 2-hour runtime.
Space Cadetwas written and directed by Liz W. Garcia, who was once tasked with writing a draft ofPrincess Diaries 3. Garcia is also known for co-writing the popular 2022 Netflix romantic dramaPurple Hearts.
