The surprise success of Interceptor proved a modern take on Under Siege can work - even without Steven Seagal. Die Hard was a breath of fresh air for action cinema in the late '80s, as the genre had largely been dominated by the muscle-bound antics of Arnold Schwarzenegger and Sylvester Stallone. Action movies had become largely concerned with big body counts and making their heroes borderline indestructible, but Die Hard laid out a new blueprint. Bruce Willis' John McClane was a very human character with a receding hairline, a failing marriage and he bled - often quite heavily - when injured. The movie's structure of stranding an everyman hero in the middle of a siege also became a subgenre of its own.
The '90s were filled with similiar kinds of high-concept movies, such as 1992's Passenger 57 (AKA Die Hard on a plane!), Cliffhanger (...on a mountain!) or Speed (... on a bus!). Like any dominant movie trend, audiences tired of this formula, and movies like The Matrix and Spider-Man ushered in a new wave. One of the most famous Die Hard riffs of this era were the Under Siege movies. The first entry arrived in 1992 and saw Steven Seagal's cook - who turns out to be an ex-Navy SEAL - having to fight back against a terrorist takeover of a battleship. The movie was both a critical and commercial success and cemented Seagal's stardom.
The actor returned three years later for Under Siege 2: Dark Territory, where Seagal's Ryback has the misfortune of being on a passenger train when a new group of terrorists take it over. The sequel grossed much less than the original, and while talk of a possible third entry occasionally surfaced in the years that followed, nothing came of it. This is likely due to waning interest in the subgenre itself after the '90s ended, though the success of Netflix's Interceptor proves there's still room for the "Die Hard on an X" movie. Interceptor cast Elsa Pataky as an army officer fighting off an invasion of a mission interceptor platform that is the only hope of preventing a nuclear attack on America. Interceptor is a very flawed movie and its reviews have reflected that, but its lean story, bruising fight scenes and cheesy tone shows there's still an audience for movies like Under Siege, which is currently getting rebooted.
In 2021, it was confirmed that director Timo Tjahjanto would be helming an Under Siege reboot for HBO Max. There's still no confirmation on what this remake's story will be, but having a filmmaker of Tjahjanto's - who might direct a Night Comes For Us spin-off too - talents inspires confidence the action will be spectacular. It's also unknown if Steven Seagal will return, though given the mountain of accusations against the star in recent years - from assaulting stuntmen to many reports of sexual harassment and assault - even a cameo feels very unlikely.
Seagal himself was a key component of why the Under Siege movies were so successful, but Interceptor shows a reboot can sell itself on the concept alone. Instead of Under Siege's hero being a badass from the beginning, Tjahjanto's remake can emphasize the Die Hard / Interceptor approach of an everyman or woman character having to raise to the occasion. Pataky wasn't exactly known as an action star before Interceptor - which has a Chris Hemsworth cameo - but she acquitted herself very well and showed it can be just as compelling to watch a protagonist struggle and barely manage to save the day. Seagal famously rarely let himself get hit by opponents in his films - let alone hurt - but adding this more vulnerable side to the new protagonist of Under Siege will add a fresh dynamic.
