User Reviews

An absolutely wonderful film, beautifully made.
24 September 1999 | by (USA) – See all my reviews

This is an outstanding adaptation of a really weird story. Although it was made for television it was shot in 35mm and frankly, it is better made than many theatrical features done at the same time. The casting is wonderful and the production values are, as usual, outstanding.

Jeremy Brett is a delight as Holmes; his 'most winning woman' speech to Watson ranks as one of my favorite scenes in this entire series. Edward Hardwicke gives him able support.

This story featured the first chase scene ever written in a detective story, and it's staged beautifully.

It's a pleasure to watch this series after suffering through the arch, camp, or (worst of all) deadly serious Holmes films made by so many other actors. THE SIGN OF FOUR is an excellent picture by any standard and a lot of fun, period.
