Amy Schumer has earned the title of movie star with her upcoming lead in the Universal Pictures feature “Trainwreck,” but according to the Emmy-nominated comedian, she didn’t think she had a chance to be featured in the summer comedy. At a press conference at CinemaCon, the convention of the National Association of Theatre Owners, in Las Vegas Thursday, Schumer dished about who she thought would earn the leading role. 

Despite her screenplay being based on her own life, the 33-year-old actress and writer revealed she initially believed supermodel turned “The Other Woman” film star Kate Upton, or possibly even Britain’s Duchess of Cambridge, Kate Middleton, had a better chance of landing the part of Amy, a New York magazine writer appalled by the idea of love. “I really did not expect to be cast in a lead role,” Schumer said. “Believe it or not, most of us women have such great self-esteem that we expect all of our dreams to be realized. I thought I would be giving notes to Kate Upton."

“Kate Upton, Kate Hudson, a Kate, Kate Middleton, I don’t know,” Schumer said when asked to expand on who she thought would be cast in the title role.

And despite beating her imaginary competition for the gig, Schumer said she is fearful the personal touches she put in the film's script may leave her single forever. “I’m probably going to die alone now,” she joked. “Everything I write is super personal, my stand-up, my show ['Inside Amy Schumer']. I’ve been an oversharer my whole life. I think it's just a mix of having a boundary-less mother and just demanding honesty and authenticity from people.”

And while “Trainwreck” may have consequences on her personal life, Schumer said she is thankful for filmmaker Judd Apatow’s work on it. Apatow, who is best known for films such as “Knocked Up" and "The 40-Year-Old Virgin," directed and helped produce Schumer's big-screen debut. 

“He has such a good sense of balance,” Schumer gushed of the filmmaker, calling him a “huge influence” on her scriptwriting. “[Without him] this movie, I don’t even know what it would look like.”

Schumer, who was present at CinemaCon to accept her award for Breakthrough Performer of the Year at the convention's Big Screen Achievement Awards, expanded on her "Trainwreck" casting predictions onstage at Universal’s 2015 slate presentation at Caesars Palace April 23. "Maybe, I'm like really pretty," Schumer said of her first thought after being cast in the feature. "But then my stunt double was a guy," she quipped. 

"Trainwreck" premieres in theaters July 17. The movie also stars Bill Hader, John Cena, Tilda Swinton, LeBron James and Brie Larson.
