A fun 'Mission: Impossible' Easter egg on movie-tracking app Letterboxd lets users be IMF agents

• "Mission: Impossible — Dead Reckoning Part One" was released on July 12.
• After users review it on movie-tracking app Letterboxd, a message says the review will "self-destruct."

For any fans of the "Mission: Impossible" series who have always wanted to know what it's like to be a part of the fictional Impossible Mission Force, or IMF, the movie-tracking app Letterboxd is helping make that dream a reality.

Letterboxd, which lets its 9 million users log and review movies, has added small Easter eggs for films before, like changing the heart icon from orange to pink for users reviewing "Barbie," or switching the eye icon that indicates you've seen a movie from green to blue for "Dune," but this one is a little more elaborate.

When you review any of the "Mission: Impossible" movies ("Mission: Impossible," "Mission: Impossible 2," "Mission: Impossible 3," "Mission: Impossible — Ghost Protocol," "Mission: Impossible — Rogue Nation," or "Mission: Impossible — Dead Reckoning Part One"), instead of Letterboxd immediately posting your review, a "message" from the IMF appears.

Like any superfan knows, the IMF's leader (known as the Secretary) will "disavow" any IMF agent, like Tom Cruise's Ethan Hunt, who gets caught — and that's exactly what the IMF threatens to do to the Letterboxd user.

Then, in true "Mission: Impossible" fashion, the message is set to self-destruct.

Thankfully, "Ethan" is able to save your review from self-destructing and restores your access to Letterboxd.

Once again, Ethan Hunt saves the day.

"Mission: Impossible — Dead Reckoning Part One," which Insider's Eammon Jacobs called "a jaw-dropping masterclass in action," is in theaters now.
