We love horror films.

But sometimes, we think there just aren't enough of them. So, with Halloween approaching, we've decided to celebrate the horror movie mash-up phenomenon, which turns ordinary films and TV shows into the gore flicks we love.

The best are below. You won't believe how good Mrs Doubtfire looks...

Home Alone

Best Bit In The Trailer: Quiet possibly the build-up. With that '80s low-budget horror music and the Carrie-esque storyline going on, it's a promising crescendo.

And the climax delivers. Just look at his face at 00.47.

We'll never look at Kevin McCallister in the same way again.

Best Scene If It Was A Film: It would only take a few minor alterations to turn Home Alone into a Saw-style terror flick. 

You've got the psychotic killer, the graphic murder scenes, and above all, some damned creative denouements.

We'd like to see one long scene, a gross-out bloodbath, where a series of booby-traps are set off in the kitchen, triggering flying knives, cheese-wire and toastie-makers.

To be honest, if this was real life, we're sure that the falling iron would have smashed Marv's scull, and that Harry's brains would be all over the walls after that swinging paint-tin hit.

Oh well. We'll just have to stick to our sketching. Though we have run out of red felt-tip.
