IIRC a landmark trial in early post-WW2 years resulted in it being impossible for third party to own complete rights for someone's natural likeness or other natural features (like voice, which was specific case involved). So they can't win the right to prevent distribution, they can win the right to use the likeliness, but for distribution they would need to have active contract with Mangione that they are representing him for that, which I somehow doubt being the case.
