Difference between R Rated and NC17

I'm from the UK and here our film ratings are

U - Universal
PG -Parent Guidance
PG-13 Same thing as PG
12 - Anyone over 12 can watch this
15 - Anyone over fifteen can watch this
18 - Same as 12 and 15

Since this site doesn't have English ratings and I'm a bit thick - can someone tell me the difference (If there is a difference) between R Rated and NC17

correct me if i'm wrong, but r - restricted, which means under 17 requires accompanying parent/legal guardian, and nc-17 - no children under 17

hope this helps?

@Hi_We'reOneDirection
Yeah! Here we have:

G: general audience
PG: Parental Guidance ("intense" scenes, cartoon violence, kiss)
PG-13: Material unsuitable for children under 13 (maybe a light fluffy sex scene some cussing, one F word)
R: Restricted (you can't get in if your a minor unless a parent or adult is with you. Or unless you have a fake id ;) Bit more intense sex, heavy violence, dirtier jokes, as many F bombs as needed)
NC-17: No children under 17 permitted. (Nudity in some cases, longer scenes of thrusting, oral sex simulation, crotch shots even, stuff that would eternally scar a young child lol A baby step away from full on porn basically)

Thank you sweets x
Like I said we don't have R Rated or NC 17 but we have PG and PG 13 here in England

This was a massive help *sending lots of love and good thoughts*

@JustBloo.
NC-17 also includes full on gore porn ;P don't forget the blood

@Call_Me_Godot
Ahhh yes!! How can I forget the blood??? Lol Confession time...I have only seen about 2 NC-17 rated films (not counting a few pornos) and neither had gore lol They were romances

@Hi_We'reOneDirection
Glad I could be of assistance Cx
