Is Escape Plan 4 about to break out of development silence? While there has been no confirmation from Lionsgate or the cast, a wave of speculation is circulating online suggesting that a fourth installment in the high-stakes prison-break franchise might be quietly in the works — possibly reuniting action legends Sylvester Stallone and Dave Bautista.

The rumors gained momentum after Stallone posted a cryptic image to his Instagram featuring a blueprint of a futuristic prison facility, accompanied by the caption “Always planning the next move.” Though it wasn’t explicitly tied to the Escape Plan series, fans immediately started theorizing that the post was a tease for another chapter in the franchise that began in 2013.

According to fan forums and YouTube channels dedicated to action cinema, Escape Plan 4 is allegedly being developed as a more grounded, gritty return to the original film’s style, with less reliance on sci-fi tech and more focus on raw strategy and claustrophobic tension. Whispers suggest a potential setting in an abandoned cold-war era facility in Eastern Europe — a prison long thought decommissioned, but still operating in secret.
