Yes they are. I did Jet2 two years ago and had the same results. Both in the top 10 for their ‘Hollywood’ terms.
Duplicate content is an issue in English, but if your template isn’t identical or your content is over 40% different (put a dual rss feed on it for the content), its not an issue.
To be fair, I have several sites ranking with duplicate content…I think its more about back links.
I was going to mention the dupe content issue but decided not to muck-up the point of the post. It can be an issue with English sites but as of today I haven’t seen it as an issue, and I have at least 5 instances where it could be in 4 languages. These sites are where my conclusions are drawn from.
