But yes, there was such a moment in his career — and its name is "The Critters 3" (1991) by Kristine Peterson. This isn't a typo or a joke: DiCaprio's feature film debut happened in the third installment of a cult but long-tired franchise about furry alien devourers.
The plot follows early '90s trash formula to a T: hairy space monsters end up in a Los Angeles apartment building and start hunting the residents. Somewhere nearby lurks a space bounty hunter, but don't expect help from him — he's become prey himself.

The film went straight to video and earned neither box office success nor critical love. Reviews sounded like death sentences: "The plot is anemic, the special effects are weak, and belonging to the 'little monsters' genre is a curse in itself" (Apollo Guide). "The film is notable only for being DiCaprio's debut" (Film Frenzy). And Sunday Times (Australia) gave it a laconic rating: 0 out of 5.
And that's probably the only thing "The Critters 3" is remembered for today. It became that starting point — the lowest possible beginning for an actor who later conquered Hollywood and won an Oscar.
And that's exactly why the film is worth seeing at least once. To appreciate how far someone can go who once starred in a movie with a zero on the "Tomatometer." Earlier, we at zoomboola.com told you about the series "The Night Manager" — when Hugh Laurie proved he could be scarier than any villain.
