Generally, in most common law jurisdictions, a will is void if it was made prior to a marriage, unless it appears from the will that it was made in contemplation of the marriage. A new will must be executed after a marriage takes place.Although you should check with a local attorney on the specifics because I am not admitted to practice in CA and I do not know where the Will was created and where your father resided. So based on what jurisdiction will control you  should contact a local attorney to ask about whether that jurisdiction revokes a Will after marriage. But in general a Will is revoked upon a marriage and that would apply to a pour over Will. A trust sometimes can survive but not from a pour over Will. Again please call a local representative to verify the specifics for the correct state law governing this transaction and Good luck with everything.
