Spoilers for Bullet Train will follow.
Bullet Train is now available in cinemas, and there are a few surprise appearances in the film.
Ryan Reynolds of Deadpool makes a surprise appearance as Carver, an assassin who was meant to be on the train rather than Brad Pitt's Ladybug, who was responsible for killing The White Death (Michael Shannon)'s wife.
Reynolds' involvement in the film was brief, appearing in only a flashback, but the performance received positive feedback from fans, who commented on their thoughts on Twitter.

Reynolds wasn't the only actor to make a surprise appearance, either. Magic Mike star Channing Tatum plays a train passenger who crosses paths with Ladybug in a slightly different role.
"You're INSANE!! Watching Tatum and Ryan Reynolds in the #BulletTrainMovie #BulletTrain is the most insane film I've ever seen." One person tweeted.
Channing Tatum and Ryan Reynolds in the #BulletTrainMovie #BulletTrainARE YOU INSANE!! Other than Ambulance, this is the most insane film ive seen this year.
I KNEW IT WAS IN BULLET TRAIN OF RYAN REYNOLDS.
Saw Bullet Train and did not know Channing Tatum was there. How funny. How cool that he, Brad, and Sandra were in one another's films? And of course, SANDRA BULLOCK!
"Saw Bullet Train. Did not know Channing Tatum was in it. He was so funny. How cool that he, Brad, and Sandra were in each others' films," another added, referring to Pitt's brief appearance in The Lost City and Bullock's role as Ladybug's handler in Bullet Train.
Fans and critics have all agreed to give the action comedy film, which starred Brad Pitt.
"Bullet Train is an excellent film to watch with a crowd if you're looking for a non-stop action ride," according to Digital Spy in their review. The game's cast and some truly left-field references (such as Thomas the Tank Engine) will give you many laughs.
"In other words, the fun here is very much in the journey, not the destination, but it's certainly a lot of fun while the ride is going."
