For these last two, even if other countries were involved, these are mostly American movies (listed as such on Wikipedia for example).
In some cases there is no clear origin between two countries, but I don't think it is the case here.
Multiple-countries origin is clear for some titles, like Power Rangers Zeo mentioned above. For that one Wikipedia also mentions also US/JP as origin.
