Continuity mistake: Felix pushes the fire alarm button and exits the building. As his buddy Danny reaches him, it's obvious that multiple takes of the scene have been made, since some extras that were meters ahead of him are just passing him by at the very first cut. (00:04:30)
Continuity mistake: The day he got expelled, Felix is having lunch with his parents. During close-ups he is eating with the spoon that is still on the table in the other shots. (00:06:00)
Continuity mistake: During the whole scene with Vanessa and her friend attaching election posters, their hands switch position inconsistently between shots. (00:07:00)
Revealing mistake: When Felix talks breaking the fourth wall about the mysterious, vicious "Roxy", he shows her twitter page. The latest tweet is dated Mar 10. Since the school at that moment still has to issue the report cards for the first semester, it seems a little too far ahead in time. (00:08:40)
Revealing mistake: As Felix recollects the time when he and Vanessa were dating, he mentions it happened in their freshman year. The Roxy tweet that broke them up is dated 12 Nov 2014. When they show Felix's report card, it says it's for the 2014-2015 year, so it would merely be a couple months before. (00:09:10 - 00:15:40)
Revealing mistake: When Danny is hacking Twitter through brute force, the code executed on screen is not at all a hacking tool, but simply prints jibberish - actually I googled some lines I could easily pick up without pausing, and they were from a past year finalist of the The International Obfuscated C Code Contest. Entirely harmless easter eggs, certainly not hacking or cracking material. (00:10:35)
Factual error: When Felix reveals Roxy/Stacy's IP to the world, it is 195.243.245. That is not a valid IP, it is missing the fourth octet. (00:14:00)
Continuity mistake: When the pizza girl uses the net to knock the model helicopter off the tree, her bag is in plain sunlight in the faraway shots, and under the tree shadow in the closer views. (00:24:20)
