Phone Booth

This is the 2003 thriller film [Phone Booth], directed by Joel Schumacher and starring Colin Farrell. It's a movie that depicts a suffocating psychological battle taking place inside a public phone booth, which are rarely seen nowadays, and it's almost a one-man show for the lead actor, Colin Farrell. An egocentric and hypocritical celebrity agent, Stu (Colin Farrell), finds himself in a situation where he receives a call in a public phone booth and is threatened by a sniper. A murder occurs around the booth, and as police swarm the scene, he becomes a suspect and the incident unfolds while he's isolated. It's a work that received good reviews for maintaining a tense atmosphere throughout the movie with the simple premise of 'If you hang up, you die.' For your reference, the voice of the sniper who threatens the protagonist in the movie belongs to actor Kiefer Sutherland, who played the lead role of Jack Bauer in the American drama series (24).
