If you are in Cologne this week, you will find the place overtaken by cheerful nerds, as Gamescom, the world's biggest gaming event, descends upon the city once again. Over 300,000 people are expected to visit the Koelnmesse to play upcoming games and enjoy each other's company, to the extent that it's possible to enjoy anyone's company in a giant crowded convention hall with woefully insufficient food options. The event began, as is now tradition, with a showcase of games (pdf) whose publishers could afford the hundreds of thousands of euros necessary to show a trailer on an official livestream. As ever, I am here to spare you from watching a full two hours of trailers and pick out the most interesting stuff. Call of Duty: Black Ops 7 was the big opener: our reporter Alyssa Mercante got a full introduction to its futuristic military paranoia, which you can read about later this week.

It's not as delightfully inventive or surprisingly philosophical as "The Lego Movie," but the Batman-themed spinoff is every bit as funny and a lot more action-packed. "The Lego Batman Movie" gets some added zing from a cast of characters that includes not just the "Bat family" of Robin (Michael Cera) and Batgirl (Rosario Dawson) but also the Justice League, a fair number of DC villains and -- just for the heck of it -- King Kong, Sauron and Lord Voldemort. So far, this is the most "anything can happen" comedy of 2017. "Kill Switch" (available June 16) Dan Stevens continues his evolution from "Downton Abbey" hunk into science-fiction/fantasy star here, where he plays an ex-NASA pilot who takes a job with a private company exploring a mirror Earth. The film's big gimmick is the whenever the hero is in the world known as "The Echo," the perspective shifts to first-person, replicating the feel of a video game.

Apple's personal assistant Siri is known for its Easter eggs and its oddball answers to questions like, "What is the meaning of life?" Now, its latest trick will help you get in touch with your inner Dark Knight. The Lego Batman Movie, released last Friday, features the voice of Siri as the Batcave's computer. So, naturally, Apple has teamed up with Warner Bros. to cross-promote the animated film. If you say, "Hey, computer!" or "Hey, 'puter!" into Siri, she responds to you as if you're the tiny, plastic Caped Crusader.

Not only was LEGO Batman insanely popular, it was insanely fun (and, frankly, just insane). If you haven't enjoyed it yet...you should really sneak away on your lunch break and amend that. It was the most enjoyable Bat-flick I've watched in years. And if you don't think it's for serious nerds...I challenge you to name every D-List villain in the opening scene. I've been reading comics for over thirty years and I still had to Google some of them to make sure they weren't simply made up (no, seriously, there really is a Condiment King)!
