Avengers: Doomsday Cast Drops Hilarious 'Silence Your Phones' Theater PSA

Marvel has a piracy problem, and it's fighting back with comedy. The studio released a humorous new video with the message "Please silence your phones," captioned "Assemble respectfully" on social media on September 28, enlisting the massive Avengers: Doomsday cast for a theater-etiquette PSA with a very pointed subtext.

The video opens with Thor attacking Robert Downey Jr.'s Doctor Doom — already worth the price of admission — before cutting to the MCU actors seated in a theater. The joke lands when Simu Liu's phone begins to ring, with Florence Pugh's Yelena at the center of the chaos. It's the kind of self-aware, star-powered bit that only a franchise this big could pull off.

A Cast of Thousands (Almost)

The PSA features a staggering roll call: Pedro Pascal, Vanessa Kirby, Tenoch Huerta, Winston Duke, Chris Hemsworth, Anthony Mackie, Sebastian Stan, Letitia Wright, Channing Tatum, Rebecca Romijn, James Marsden, Wyatt Russell, Hannah John-Kamen, and Danny Ramirez all appear. Getting that many A-listers in one sketch is a flex in itself — and a reminder of just how enormous the Doomsday ensemble really is.

The timing is no accident. The video arrives after recordings of the new Avengers: Endgame Encore scenes circulated on social media — the kind of theater-filmed leaks that studios dread. Endgame Encore still topped the box office with an estimated $86M worldwide in its opening weekend, but the leaked footage clearly stung enough to warrant a response.

Marvel's Most Secretive Project

The PSA doubles as a mission statement for the film's marketing. Doomsday is shaping up to be one of Marvel's most secretive projects, with marketing keeping many plot details under wraps. The studio is clearly determined to protect its surprises — and it's asking fans, nicely and then not-so-nicely, to help.

It's a clever move: turn the anti-spoiler lecture into content fans actually want to watch. Whether it stops anyone from filming in theaters is another question entirely, but as a piece of marketing, "Assemble respectfully" is about as Marvel as it gets.

Leaks, Laughter, and Damage Control

The subtext here is doing a lot of heavy lifting. The PSA's arrival on the heels of leaked Endgame Encore footage circulating on social media makes the "silence your phones" message land with a wink — this isn't just about etiquette, it's about enforcement. Studios have tried everything from stern warnings to legal threats to stop theater recording; Marvel's approach is to make the anti-piracy message itself go viral, enlisting Thor, Yelena, and Doctor Doom as the messengers. It's a distinctly modern solution: if you can't beat the content machine, feed it something better. And the sheer star wattage on display — Pascal, Kirby, Mackie, Stan, Wright, Tatum, and a dozen more — turns a scolding into an event. There's also a strategic layer: with Doomsday positioned as one of Marvel's most secretive projects, every leaked frame is a marketing plan unraveling. An $86 million worldwide opening for Endgame Encore proves audiences still show up; the PSA is Marvel's way of asking them to protect the experience they're paying for. "Assemble respectfully" might be a joke, but the studio is dead serious.
