The six remaining acts - Little Mix, Misha B, Amelia Lily, Janet Devlin, Marcus Collins and Craig Colton - will each perform a song featured in a classic film.
The X Factor has featured a movie-themed week in the past, including 2009's series - which famously saw Louis Walsh challenging Simon Cowell's choice of a song from the little-known cult film Gummo.
On that occasion, acts including Olly Murs, Stacey Solomon and Joe McElderry sang songs from the films Pulp Fiction, Ferris Bueller's Day Off and The Lion King.
Last week, the finalists sang tracks by Lady GaGa and Queen, with Kitty Brucknell being eliminated.
The X Factor airs on Saturday at 8.15pm on ITV1.
