Missed during the busy Comic-Con weekend, the press release from Marvel Studios which accompanied the first Spider-Man: Homecoming concept art has revealed that an awful lot of cooks have been in the reboot's kitchen. While it was thought that the team of Jonathan Goldstein and John Francis Daley (Horrible Bosses, Vacation) wrote the screenplay alone, we know now that director Jon Watts also contributed (his writing credits include the movies he's directed like Clown and Cop Car).
Christopher Ford worked on that draft alongside the filmmaker, and he actually teamed with Watts on the movies listed above and wrote Robot & Frank alone. Finally, one more writing team mentioned is Chris McKenna and Erik Sommers. They worked on the upcoming Jumanji reboot together, while Sommers most recently penned The LEGO Batman Movie. He's also written for TV shows like Happy Endings and American Dad. McKenna meanwhile has written many of Community's best episodes.
The order these guys worked on Spider-Man: Homecoming in is unclear, but Watts, Ford, McKenna, and Sommers all inspire more confidence than Goldstein and Daley. Still, that's a lot of writers!
