Style icon Ali MacGraw was almost forced to get her trademark crooked teeth straightened at the start of her acting career, but was saved from dental interference when her director's assistant spoke up against it.

The model-turned-actress shot to fame in 1970 following the success of Love Story, proving that wonky teeth are no obstacle to Hollywood success.

But her early years were plagued by worries her unusual dental make-up would put movie-makers off.

MacGraw recalls: "When I first started to break into acting, JOYCE SELZNICK, the casting director, suggested I get my teeth fixed. Her PA whispered, 'Don't you dare.' I didn't; they remain crooked to this day."
