The film described, where Sylvester Stallone portrays a structural security expert who must escape a maximum-security prison he himself designed, with the assistance of a fellow inmate played by Arnold Schwarzenegger, is indeed *Escape Plan (Review)*. Released in 2013, this action thriller perfectly matches the plot points, as Stallone's character, Ray Breslin, is renowned for his ability to find flaws in any correctional facility, only to be double-crossed and incarcerated in "The Tomb," an ultra-secret, high-tech prison where he must apply his expertise to break out. Schwarzenegger's character, Emil Rottmayer, becomes his crucial ally in this daring endeavor.

What made *Escape Plan* particularly noteworthy for many fans was the rare opportunity to see two of the biggest action stars of the 1980s and 90s, Sylvester Stallone and Arnold Schwarzenegger, share significant screen time as co-leads. While they had previously appeared together in *The Expendables (Review)* franchise, *Escape Plan* marked their first true pairing in starring roles, a collaboration long anticipated by audiences. The film capitalized on their combined star power, offering a blend of brain and brawn as their characters worked together to outsmart the prison's sadistic warden.

Despite receiving mixed reviews from critics, *Escape Plan* proved to be an international box office success, grossing over $137 million worldwide against a budget of $54-70 million. Its global appeal led to the creation of a film series, with Stallone reprising his role in two sequels, *Escape Plan 2: Hades* and *Escape Plan: The Extractors*. The movie is a testament to the enduring popularity of its legendary leads and the timeless appeal of a clever prison break (Review) narrative.
