Love is a Splendid Illusion, also known as Bed and Don't Tell, [1] is a 1970 British sex comedy film directed by Tom Clegg and starring Simon Brent and Andrée Flamand.

There is more to the plot than in most recent offerings on the same lines and the acting is adequate; but in all other respects it's the mixture as before, with the girls stripping at the slightest pretext and the protagonists making love to the visual accompaniment of thundering surf.

The cast is entirely without well known star names, and though the acting does not suggest any discoveries, it is competent, and Simon Brent, as Christian, certainly has looks and wears clothes handsomely.

You'd think that any film featuring handsome Simon Brent as a trendy young stud designer, romping merrily between one steamy bedroom scene and another, might at least hold your attention.

But by the time the hero's final conquest (and they are innumerable) gets her gear off and gets down to business, most of the audience is yawning and scratching, checking their watches or just plain snoring.
