Editing Michael Rennie (section)

===Supporting actor at Fox===
Rennie was second-billed in ''[[Sailor of the King]]'' (also known as ''Single-Handed'', 1953), playing an admiral, as supporting actor to [[Jeffrey Hunter]]. He was leading man to [[Jeanne Crain]] in a thriller, ''[[Dangerous Crossing]]'' (1953), which re-used sets and props from ''[[Titanic (1953 film)|Titanic]]'' (also 1953), for which Rennie spoke the closing narration. He had a showy role as [[Saint Peter]] in ''[[The Robe (film)|The Robe]]'' (1953), the first movie in [[CinemaScope]] and the biggest hit of the year. The star was Richard Burton, who had essentially taken Rennie's place on the Fox lot as their "resident British star".

Rennie supported Tyrone Power once more in ''[[King of the Khyber Rifles (film)|King of the Khyber Rifles]]'' (1954), as a brigadier in British India, then he played his first villain for Fox, an evil Khan in the "eastern", ''[[Princess of the Nile]]'' (1954), opposite Jeffrey Hunter. He reprised his role as Peter in ''[[Demetrius and the Gladiators]]'' (1954) and was lent out for ''[[Mambo (film)|Mambo]]'' (1954).

In ''[[Désirée (film)|Désirée]]'' (1954), Rennie played the future [[Charles XIV John of Sweden]] opposite [[Marlon Brando]] as [[Napoleon Bonaparte]]. The film was popular although not as highly regarded as other Brando films from this time. ''[[Soldier of Fortune (1955 film)|Soldier of Fortune]]'' (1955), was another hit, with Rennie as the head of British police in Hong Kong supporting [[Clark Gable]] and [[Susan Hayward]].

On TV he played the attorney in an adaptation of ''The Letter'' (1955) with [[John Mills]]. He also received good reviews for his performance as an art dealer in "A Man of Taste" (1955) for ''Climax'' with [[Zsa Zsa Gabor]].<ref>{{cite news |title=TV Review: ' Climax' Show Melds Felony and Comedy |first=J.

"You have greater performances as opposed to those in a filmed series", he said. "You are able to build and sustain a role in live TV whereas you have the problem of cutting, stopping and starting in a filmed show."<ref name="page">{{cite news |title=The Third Man: Harry Lime Will Be Newest TV Hero |url=https://latimes.newspapers.com/image/381315508/?terms=The%2BThird%2BMan%3A%2BHarry%2BLime%2BWill%2BBe%2BNewest%2BTV%2BHero |last=Page |first=Don |newspaper=Los Angeles Times|date=7 June 1959 |page=G8 |url-access=subscription}}</ref>

Based on the positive reaction to his two turns as the Apostle Peter, Fox assigned him another third-billed, top-tier role as a stalwart man of God, [[Franciscan]] [[friar]] [[Junípero Serra]], who, between 1749 and his death in 1784, founded [[Spanish missions in California|missions]] in [[Alta California]]. The film was ''[[Seven Cities of Gold (film)|Seven Cities of Gold]]'' (1955), with [[Richard Egan (actor)|Richard Egan]] and [[Anthony Quinn]].

His next film was ''[[The Rains of Ranchipur]]'' (1955), assigned him fifth billing after the lead romantic teaming of [[Lana Turner]] and [[Richard Burton]]. As Turner's character's [[cuckold]]ed husband, Lord Esketh, Rennie maintained his typical dignity and stiff upper lip. He supported [[Ginger Rogers]] in ''[[Teenage Rebel]]'' (1956) and had a good role as the man murdered by James Mason in ''[[Island in the Sun (film)|Island in the Sun]]'' (1957), Darryl Zanuck's popular melodrama. His contract with Fox then wound up.
