Constance Worth (born Enid Joyce Howarth; 19 August 1911 – 18 October 1963) was an Australian actress who became a Hollywood star in the late 1930s.

She was born in Sydney, Australia in 1911, the youngest of three daughters of businessman Moffatt Howarth and his wife Mary Ellen (née Dumbrell).

Her film debut was in the title role in the Cinesound movie The Squatter's Daughter (1933), produced and directed by Ken G. Hall.

Hall claimed Howarth's first screen test showed "light and shade, good diction, no accent and (that) she undoubtedly could act with no sign of the self-consciousness which almost always characterised the amateur.

[9][10] In late 1933, Smith's Weekly raved enthusiastically about the young actress; "Young Joy Howarth who leapt into publicity when she became the Squatter's Daughter a few months ago, is just the big hit nowadays...."[11] She had a supporting role in Hall's next film, The Silence of Dean Maitland (1934), which was also a box-office success.

Because she appeared opposite established Hollywood actor Vinton Hayworth, RKO decided to give her a new name "Constance Worth".

Her next role was in Willis Kent's 1938 exploitation quickie, The Wages of Sin (1938), playing a young woman lured into prostitution.

[35] Worth was fourth billed in the gangster B film Borrowed Hero (1941) at Monogram and The Dawn Express (1942) at RKO.

[36] Back at Columbia, she was billed third in Boston Blackie Goes Hollywood (1942),[37] then at Universal, she was uncredited in When Johnny Comes Marching Home (1942).

[38] She went to work as a waitress at a drive-in restaurant, which led to an item in a gossip column and drew the attention of Harry Cohn.

[41] At Columbia, she had a supporting role in Let's Have Fun (1943) and She Has What It Takes (1943), then was uncredited in Crime Doctor (1943), Appointment in Berlin (1943), Dangerous Blondes (1943), My Kingdom for a Cook (1943).

She had billing in The Crime Doctor's Strangest Case (1943) and had a decent role in Klondike Kate (1943), directed by William Castle.

At Columbia, she was Charles Starrett's leading lady in the Westerns Cyclone Prairie Rangers (1944) and Sagebrush Heroes (1945).

[43] For Sigmund Neufeld at PRC, she played a supporting part in The Kid Sister (1945) and was unbilled in Dillinger (1945) at Monogram.

[44] Worth had a supporting part in PRC's Why Girls Leave Home (1945) and Monogram's Sensation Hunters (1945), and a minor role in RKO's Deadline at Dawn (1946).

Denis O’Brien comments that even in 1939 "the Weekly still was dredging the Howarth saga" in its report on her latest film Mystery of the White Room (1939).
