Watching movies is haram to start with (for various reasons, some of which are: it has pictures, it has music, you look at non-mahram members of the opposite sex - often wearing unislamic clothing, etc.). It is also a waste of time and mostly depicts unislamic things such as violence and extra-marital relations, mixing of the sexes, portraying unislamic environments and situations, etc. The same goes for soap operas. So how can refraining from a haram thing be used as grounds for divorce?
I think the wife blackmailing the husband in such a way may be used by the husband as grounds for divorce.
