Greg Berlanti’s planned gay-themed young adult movie, Simon vs. the Homo Sapiens, continues to come together. The film already has Jurassic World’s Nick Robinson attached to star, and now he has company, with THR reporting that Scouts Guide to the Zombie Apocalypse’s Logan Miller has joined the film.

Based on Becky Albertalli’s novel, the film will follow, ‘a gay teen named Simon who has not come out to his classmates. But when an email he sent to a boy (that he’s never met) falls into the hands of class clown Martin, Simon finds himself in a complicated situation when he’s blackmailed into helping Martin get to know his best friend Abby, the new girl in school.’

Robinson will play Simon, while Miller will be his blackmailer, Martin.

Isaac Aptaker and Elizabeth Berger wrote the script for the movie, although it’s not clear when it might shoot. The likelihood is that with Berlanti still busy on his DC TV series, it will begin lensing once the latest seasons of Arrow, Flash, Legends Of Tomorrow and Supergirl have wrapped in the Spring.
