Production has begun on the "Alien" series.

The prequel is filming in Bangkok without some of its lead actors
Production on FX's Alien series has begun in Thailand, but without its stars, who are members of the Screen Actors Guild of America (SAG-AFTRA), due to the ongoing strike.

Sydney Chandler, confirmed in May this year for the female lead, is joined by Alex Lawther and Samuel Blenkin in the lead male roles. Alex Lawther, star of Netflix's youth drama "The End of the ***ing World," will play a soldier named C.J., while Samuel Blenkin ("Black Mirror") will play the other main character, Boy Cavalier, a CEO. Supporting actors include Essie Davis ("Lamb of God") as Sylvia and Adarsh Gourav ("White Tiger") as Slightly.

The actors' contracts were signed well before the SAG-AFTRA strike began on 14 July 2023, and those who are members of the American union are not currently in Thailand working on "Alien". Production began on Wednesday, 19 July at The Studio Park, where the crew filmed scenes that do not involve SAG-affiliated actors.
