HBO Films is teasing the Oct. 20 premiere of its Alfred Hitchcock/Tippi Hedren-based tele-pic The Girl with an intriguing behind-the-scenes clip that includes interviews with director Julian Jarrold (Becoming Jane), star Sienna Miller and Hedren herself.

“The Girl” details Hitchcock’s dark and obsessive relationship with Tippi Hedren during the making of The Birds and Marnie. According to Hedren, an embittered and rejected Hitchcock ruined her career by keeping her under contract for two years, preventing her from working with other studios.

The Girl stars Sienna Miller (G.I. Joe: Rise of Cobra) as Hedren, Toby Jones (The Hunger Games) as Hitchcock, Imelda Staunton (Harry Potter and the Deathly Hallows) as his wife Alma Hitchcock and Penelope Wilton (Shaun of the Dead) as his assistant Peggy Robertson.
