1932–1936: Acting debut and early roles

Grant's role in Nikki was praised by Ed Sullivan of The New York Daily News, who noted that the "young lad from England" had "a big future in the movies". The review led to another screen test by Paramount Publix, resulting in an appearance as a sailor in Singapore Sue (1931), a ten-minute short film by Casey Robinson. Grant delivered his lines "without any conviction" according to McCann. Through Robinson, Grant met with Jesse L. Lasky and B. P. Schulberg, the co-founder and general manager of Paramount Pictures respectively. After a successful screen-test directed by Marion Gering, Schulberg signed a contract with the 27-year-old Grant on December 7, 1931, for five years, at a starting salary of $450 a week. Schulberg demanded that he change his name to "something that sounded more all-American like Gary Cooper ", and they eventually agreed on Cary Grant.

Grant set out to establish himself as what McCann calls the "epitome of masculine glamour", and made Douglas Fairbanks his first role model. McCann notes that Grant's career in Hollywood immediately took off because he exhibited a "genuine charm", which made him stand out among the other good looking actors at the time, making it "remarkably easy to find people who were willing to support his embryonic career". He made his feature film debut with the Frank Tuttle -directed comedy This is the Night (1932), playing an Olympic javelin thrower opposite Thelma Todd and Lili Damita. Grant disliked his role and threatened to leave Hollywood, but to his surprise a critic from Variety praised his performance, and thought that he looked like a "potential femme rave".

In 1932, Grant played a wealthy playboy opposite Marlene Dietrich in Blonde Venus, directed by Josef von Sternberg. Grant's role is described by William Rothman as projecting the "distinctive kind of nonmacho masculinity that was to enable him to incarnate a man capable of being a romantic hero". Grant found that he conflicted with the director during the filming and the two often argued in German. He played a suave playboy type in a number of films: Merrily We Go to Hell opposite Fredric March and Sylvia Sidney, Devil and the Deep with Tallulah Bankhead, Gary Cooper and Charles Laughton (Cooper and Grant had no scenes together), Hot Saturday opposite Nancy Carroll and Randolph Scott, and Madame Butterfly with Sidney. According to biographer Marc Eliot, while these films did not make Grant a star, they did well enough to establish him as one of Hollywood's "new crop of fast-rising actors".

In 1933, Grant gained attention for appearing in the pre-Code films She Done Him Wrong and I'm No Angel opposite Mae West. West would later claim that she had discovered Cary Grant. Of course Grant had already made Blonde Venus the previous year in which he was Marlene Dietrich's leading man. Pauline Kael noted that Grant did not appear confident in his role as a Salvation Army director in She Done Him Wrong, which made it all the more charming. The film was a box office hit, earning more than $2 million in the United States, and has since won much acclaim. For I'm No Angel, Grant's salary was increased from $450 to $750 a week. The film was even more successful than She Done Him Wrong, and saved Paramount from bankruptcy; Vermilye cites it as one of the best comedy films of the 1930s.

After a string of financially unsuccessful films, which included roles as a president of a company who is sued for knocking down a boy in an accident in Born to Be Bad (1934) for 20th Century Fox, a cosmetic surgeon in Kiss and Make-Up (1934), and a blinded pilot opposite Myrna Loy in Wings in the Dark (1935), and press reports of problems in his marriage to Cherrill, Paramount concluded that Grant was expendable.

Grant's prospects picked up in the latter half of 1935 when he was loaned out to RKO Pictures. Producer Pandro Berman agreed to take him on in the face of failure because "I'd seen him do things which were excellent, and Hepburn wanted him too." His first venture with RKO, playing a raffish Cockney swindler in George Cukor 's Sylvia Scarlett (1935), was the first of four collaborations with Hepburn. Though a commercial failure, his dominating performance was praised by critics, and Grant always considered the film to have been the breakthrough for his career. When his contract with Paramount ended in 1936 with the release of Wedding Present, Grant decided not to renew it and wished to work freelance. Grant claimed to be the first freelance actor in Hollywood. His first venture as a freelance actor was The Amazing Quest of Ernest Bliss (1936), which was shot in England. The film was a box office bomb and prompted Grant to reconsider his decision. Critical and commercial success with Suzy later that year in which he played a French airman opposite Jean Harlow and Franchot Tone, led to him signing joint contracts with RKO and Columbia Pictures, enabling him to choose the stories that he felt suited his acting style. His Columbia contract was a four-film deal over two years, guaranteeing him $50,000 each for the first two and $75,000 each for the others.
