Not the wrong tense at all. If copyright is being disputed in the courts it's about whether the copyright prevails at times relevant to the court action, not some time in the distant past. For a trailer it's about the time when it is shown. The failure to register at some past time, or the failure to post a copyright notice can easily rebut the presumption of protection, but unless these defences are raised the presumption stands.
Evidences? Please show that protection is presumed until a counter is found.
Who are you talking about? If someone has a legitimate foreign copyright, it would normally apply in the USA by virtue of international treaties, unless you want to argue that some U. S. idiosyncrasy applies.
The makers of the trailers this is fairly obvious from the context. Since they were published in the US during the time period in question foreign copyrights do not impact their US copyright status.
