Screenwriting : After Credit Scene by Ben Madeley

You could create a separate slugline that reads "Epilogue" above the slugline for this scene you want to play after the credits.

I personally wouldn't do it at all.

Are you writing it for someone else or as a filmmaker yourself? Is this for your own project, a shooting script? If so, do it as you please. It's your script until someone else shows up. I would say RUN CREDITS, then under that something like POST-CREDIT SCENE, then format the post-credit scene as you would any other. Or perhaps just note a possible post-credit scene. If working with the director and editor, say on a student project, an added scene after the credits roll could be determined after the principal photography is shot. Hope that helps!

A lot of films today have mid-credit scenes and post-credit scenes. Some scenes continue the story, and some are blooper-quality. If I strongly felt a scene needed to be presented like that - and especially if it was a post-credit scene that conveyed a surprise ending, or something like that - I'd do it like this:

EXT. CEMETERY - NIGHT - POST CREDIT:SEQUENCE

An arm juts out of the grave.

Best fortunes in your creative endeavors, Ben!

Yes, that's a great way to format a post-credit scene, Bill. Thanks for sharing. :)

Here's another good example I found online from William Martell when asked the same question:

POST CREDITS:

EXT. GRAUMAN'S CHINESE -- DAY

The red carpet for a movie premiere, (etc)

That's what I did and no one kicked me out of Hollywood.

Ben, my two cents, if you have a great idea that works, go for it. If this is a spec script, then as the writer you are suggesting what COULD be, not what SHOULD. ;) If the script incites interest, goes further, gets purchased and/or others come on board, etc, then those decision-makers will decide what works best for the final production. Best to you!

I write the scene without any special heading and leave it to the director's intuition where to place it :^}

Thanks to all the comments this has answered my questions. Thanks to Bill and Beth, you guys really helped. The script I'm writing will one day (fingers crossed) be sold, which I am fully aware that once it's handed over its their decision to keep or add certain scene. The actually credit scene I wanted to add is just for a little bit of humour that isn't necessarily needed in the main story.

Again thanks for all the help!!

Ben - after that update, I especially wouldn't do it. if it's not needed for the story there's a good chance it will just bog it down. kill your darlings.

Glad that helped, Ben! It’s your script. A stinger at the end could work for this particular story and script. At this point, the decision is yours. Without full context of the script, none of us can really say one way or the other. Best wishes with your creative endeavors, Ben. ;)
