- California Doubling: Very little of the series films in Silicon Valley or the ajoining areas featured in the show. All interiors are filmed in and around Los Angeles. Most establishing shots are however, filmed on location in and around Silicon Valley, and most real locations were filmed on location as well, such as AT&T Park, Oracle Arena, and Moscone Center.
- The Character Died with Him: Christopher Evan Welch (Peter Gregory) died partway through filming season 1. The character was Put on a Bus for the final three episodes, and died in the first episode of season 2.
- Creator Backlash:
- T.J. Miller said that the reason he left the show was because it had become too cyclical and was in danger of wearing thin. Ironically, the producers (including Mike Judge) give the same reason for their plan to write Erlich off for most of season 5 as was originally planned before Miller outright quit, as they got tired recycling the same old plots to keep him relevant to the various storylines and Miller's bad behind the scenes behavior gave them the sword to cut the Gordian knot and write out the actor. Miller's increasingly bizarre and even dangerous behavior since has given this a lot of credence.
- A year later, Alice Wetterlund accused the rest of the cast and crew of being complicit in Miller's antics, which were already at a level that should have been unacceptable even back during her time on the show. She concluded, "They can all fuck off forever."
- The Weissman Score was something created by the writers to try and convey a metric to an audience that might not necessarily be well-versed in computer programming. But the producers had Stanford researchers actually develop a legitimate equation that is slowly gaining traction in the research community.
- The middle-out compression algorithm that Pied Piper uses on the show might actually become the basis of a new theory that could truly revolutionize data compression in the real world.
- And the equation for jerking off a roomful of dicks is the subject of a genuine 12-page scientific article that's been published.
- Jian Yang's "Not Hotdog" app is available in the App Store, it can be downloaded here. And yes, it can actually tell you whether it's a hotdog or not. Unlike in the show, however, it can tell a dick from a hotdog. Jian-Yang also appeared on Bloomberg Tech's official Twitter to talk about the app, although he quickly switches to taking advantage of the audience he has to humiliate Erlich for cashing out beforehand.
- Harpo Does Something Funny: The core cast includes several seasoned improv comedians, so some of the show's dialogue comes from them riffing off of one another.
- Hostility on the Set: On July 18, 2018, Alice Wetterlund took to Twitter to accuse T.J. Miller of inappropriate, unprofessional behavior on set, writing:I hope to not ruin it for you, but T.J. Miller was a bully and petulant brat".
- Posthumous Credit: Christopher Evan Welch (Peter Gregory), died of lung cancer in December 2013 at the age of 48 and after having only shot 5 of the 8 planned episodes. Instead of recasting his role (since the series had not premiered yet), the writers wrote Peter Gregory out of the last few episodes.
- Throw It In!: The cast has a lot of veteran improv comedians who are given a lot of leeway to do their stuff. Most notably, almost all of Jared's Dark and Troubled Past is made up by Zach Woods on the spot, and he's cautioned fans that he's never tried to make it all fit together so they shouldn't try to build a coherent story out of it.
- What Could Have Been:
- Pied Pipers Skunkworks was planned as a multi-episode arc spanning most of season 3, it was abandoned, after it was believed it would be funnier to have the plan immediately blow up in their face.
- Due to T.J. Miller's schedule, as well as his lack of dedication to being on the show, with Miller often being late to shootings, and alleged clashes with co-creator Alec Berg, as well as difficulty by the writers in finding stuff for Erlich to do, the writers only planned for Erlichs bus trip to China to be temporary, with Erlich returning for three episodes in Season 5 before writing him out of the show for good. Miller declined to return at all, making his departure permanent.
- Write What You Know: Many plot elements are based on the experiences of the writers and actors.
- Mike Judge based the show on his own experiences as part of the F/A-18 program.
- The Richard subplot in "Proof of Concept" is based on some real life drama that happened to one of the writers: They were going out with a woman, they broke up, the woman kept trashing him behind his back by saying he was obsessed with her, and when the two ran into each other one day, the guy wanted to set the record straight that he wasn't obsessed with her, but the woman wasn't convinced.
- Jared's inexplicable nighttime German ramblings originate from an experience that actor Zach Woods had. According to his roommate, he awoke from a sound sleep and announced, "I hate the Jews!" before promptly falling back asleep. Woods, who is Jewish, has no memory of the event.
- Everyone mocking Dinesh's gold chain is based on an actual experience Kumail Nanijiani had in high school. Apparently the real insults were much worse.
