All the Colors of the Dark
Time Out says
Of that notable brace of early 1970s European horror flicks shot in the UK (see also 'Lizard in a Woman's Skin', 'The Living Dead at the Manchester Morgue'), this is the least known and perhaps the most intriguing. Similar in tone to 'Lizard', it concerns a young woman (Edwige Fenech) who has recently lost a child in a car wreck, and who turns – semi-willingly – to Satanism to give her back a sense of agency. The soundtrack and period fashions are predictably terrific, but it's the intense performances, psychedelic trick-shots and gripping shock scenes that stand out.
