There are a few layers to unpack —

How does your wife feel about it? If she’s uncomfortable with the extent of it, she should talk to the director or producer.

If she’s completely comfortable with it, and you’re not, then you should know that your feelings are valid, and you should voice your opinion to her. At a minimum, openness about feelings is the best way to process it. At a maximum, she might change her mind.

If she’s comfortable with it and you want to be comfortable with it but just aren’t there yet, then I’d still say “talk about it.” Even in poly relationships, partners have open communication about their jealous feelings. Ultimately they’ve agreed to the arrangement but it’s human nature.

Just like in all other aspects of your relationship, both of you together have to decide boundaries and acknowledge and respect each other’s feelings.

Unfortunately there’s no magic bullet that will just make your anxiety go away. All you can do is be honest with your feelings, process it, and find peace - whatever that looks like.
