Marketing/trailers that tried to trick audiences

A recent strange phenomenon is how Hollywood goes out of its way to hide the fact that musicals are musicals in the marketing. The trailers won't show any of the characters singing and will make it look like it's a normal movie. The reason for this seems to be that marketing teams know that some people don't like musicals, so they think they can get them to buy a ticket by tricking them into thinking a musical is not a musical and I guess hope that they won't bother doing any research beforehand. Wonka and Mean Girls are some recent examples of this.

But Hollywood does this kind of deceitful marketing all the time. Most infamously, the movie Kangaroo Jack's marketing made it look like a fun family movie with a talking kangaroo that raps, but in reality it's a comedic crime movie for adults and the kangaroo barely appears and only talks in one scene where a character is hallucinating. In fact, the movie was originally R-Rated and was going to be called Down and Under, but then was retitled and edited to a PG rating by producers because the kangaroo scene was the only think test audiences liked.

So what other movie marketing campaigns tried to basically trick audiences into thinking that the movie was going to be about something else or even of a different genre?
