The Deep End is a 2001 movie starring Tilda Swinton which is sometimes described as a re-make of a James Mason film called This Reckless Moment. In fact, both are based on The Blank Wall, a novel by Elisabeth Sanxay Holding.
I haven’t read the book, but I was first alerted to Holding’s qualities as a crime writer by Ed Gorman’s blog, and it turns out that her other admirers included Raymond Chandler and the legendary critic Anthony Boucher. She started out writing romances, with titles including The Invincible Minnie, before turning to novels of suspense, apparently as a way of making more money after the Wall Street Crash. She died in 1955.
As for the movie, I have to say I was underwhelmed. The basic premise is that Tilda plays Margaret Hall, whose son is in a relationship with an unsavoury older man. When the older man dies, and her son is implicated, Margaret tries to cover things up, only to become embroiled in a blackmail scam.
The raw material of the story is strong (the book and the James Mason film were successful) but I did find it difficult to care much for either Margaret Hall or her son, and in a story like this, it is almost always essential to have some form of empathy for the main characters. The production values of the film are high, and the Lake Tahoe area looks attractive, but I am afraid this was a thriller which thrilled me much less than I had hoped. I would, however, be very interested to learn the views of other Holding fans about her best books.
