I think there is something about the natural position his mouth between speaking his lines. He’s sort of got a sort of forced a half smile with just the corners of his mouth, that makes it look like he’s trying to hide something.
Originally he was unshaven in a rumpled overcoat and I thought that had a lot to do with his creep factor. But they’ve cleaned him up recently. Didn’t work. Still creepy.
I’ve just always assumed it’s because Trivago comes across as fake all the way across. They don’t do anything but consolidate data available elsewhere. They have a name that means nothing, but must have scored well in focus groups. They have a spokesman with no name and no memorable attributes, also straight from focus groups who want to communicate something like “reliable and trustworthy, but not old fashioned.”
So he does come across as creepy, but the whole thing is creepy. It’s like an uncanny valley of commercialism and marketing.
That, and his facile intonations, going on for a full minute - his voice is louder than a lot of commercials I hear. Disingenuous attempts at trying to be Mr. Charming-Everyday Guy.
And oh-so-slightly slurring over the “t” in “hotel”, like he’s trying to make it sound like something new.
I sort of get the “G-Man from Half-Life” feeling from him, like he learned to act like a human by watching people interact with each other but didn’t pay enough attention.
Those pictures of him on the IMDB linked above are even creepier than the Trivago commercials. And I think dracoi has it right, both the company and the spokesperson are creepy.
Trivago is based in Germany. That could explain why they used an actor who can speak German, and why the ads are a little off-putting to American ears.
