The Dark Avenger is a 1955 British historical action adventure film in CinemaScope directed by Henry Levin.

It was the prestige production for Allied Artists in 1953–54, a co-production with Associated British Pictures, to be filmed in England, shot in CinemaScope and Technicolor.

The use of CinemaScope saw 20th Century Fox became involved as partners in production and distribution on the film, as part of an arrangement between it and Allied Artists.

[8] This enabled the studios to share costs, and for Allied to take advantage of Fox's superior distribution system in foreign markets when it came to handling CinemaScope films.

[9] Joanne Dru was also imported to play the female lead; Peter Finch was cast as the main villain.

Henry Levin was chosen to direct on the basis of several swashbuckling films he had made for 20th Century Fox and Columbia.

[13] Flynn made the feature shortly after his proposed film about William Tell had not come to fruition and was in bad need of funds.

Number one, photographed (by Guy Green) in color at England's Elstree Studios, with a spanking array of period castles and costumes cluttering the lovely countryside, it all looks quite fetching.

[16] Filmink said "Errol is too old and portly to play a dashing prince; also, he shaved off his moustache, which makes him look even older" and called the film "pretty bland stuff".
