Most of the actors are signed under Equity not SAG. In the UK they are prohibited from going on strike. Warner Bros can take them to court if they refuse
@ladydragonjj
No. It depends what union the actors have contracts with. For HOTD most of the cast is British and have contracts with Equity and not SAG. The UK has very strict anti-striking rules which wont allow the actors to strike in solidarity with actors under SAG.
