Mid-70's horror series

[Mark O]

Hi, I'm trying to think of a TV drama shown mid-70's, which I think was part of a series, a wedding has taken place and as the bride and groom are walking along the church pathway after the ceremony I think she walks into a tripwire and a bag of blood hurtles down from a tree and ruins her dress (and big day), she says "who would want to do a thing like that?", the actress looked a bit like a non-smiley Nigella Lawson with long black wavy hair, any ideas anyone?

I think it's the episode of Thriller entitled Only A Scream Away - and

  Spoiler:

it isn't actually blood, just paint

.

Yes, I think that must be it Graeme, thanks for the slideshow, I'm obviously getting Hayley's face mixed up with someone else.

I was thinking the same as Graeme too Mark.
