Drama-horror could be another genre cross over i could use, which would usually include the character development of an ordinary protagonist facing everyday problems but we become aware of an antagonist haunting or simply out to kill the protagonist.
An example could be the trailer for 'knock knock'

The trailer starts with an ordinary protagonist with a typical family(see right) but soon encounters a moral issue which are the basis for many drama films, in this one it appears to be cheating.
This is further set up to be a drama with the fact that the first part is entirely dialogue driven and the main protagonists character is developed so that the audience are interested in how he deals with the moral issue.
The main protagonist appears to become a hostage in his own home, trapped and being hunted by the antagonists who, unlike in other horrors, are revealed.This cross-over is effective as we now see a developed character having to deal with horror elements as a consequence of his moral decision.
