Season 2 of Yellowstone spin-off 1923 has been delayed due to the US writers' strike.

The anticipated second season of Yellowstone spin-off 1923, starring Harrison Ford and Helen Mirren, has been delayed owing to the ongoing US writers' strike.

On June 8, NBC Montana reported that the production of 1923 season two, which is now taking place in Butte, Montana,

has been postponed indefinitely. The crew was supposed to return to Butte on Monday, but they never did.

In addition, the production is reportedly paying Butte-Silver Bow $75,000 per month to utilize the Civic Center.

They've now asked for a 10-day extension on this contract, which was due to expire at the end of the year. The City-Council Commission has yet to approve them.

According to reports, additional extension requests have not been ruled out, but the Civic Center is ready for production to resume.

However, it is uncertain when that will occur because it can only occur once an agreement with the Writers' Guild of America (WGA) is established.

The WGA is going on strike in order to negotiate better wages. Writers are paid a fee for their labor, but they are paid more if a show is popular on broadcast television.
