10 Actors Whose Brilliant Moment Of Improvisation Landed Them The Role

We end with the least experienced name on our list, but, don't let her age fool you, Dafne Keen had the wherewithal to know that she had a distinctive tool up her sleeve which would help tattoo her name onto the part of the young mutant, X-23, in James Mangold's 2017 genre-buster, Logan.

In one of the most incredible improvised moments ever to be captured on tape, Keen is seen asking Mangold if she could be given permission to perform the scene in a mixture of Spanish and English. What followed caught Wolverine himself, Hugh Jackman, completely off-guard and the two would go back and forth in a magical exchange, with Jackman having no choice but to react in true Logan fashion by demanding the young fire-cracker to 'SHUT THE F**K UP!'

If you listen really closely, you can even hear Jackman slip out of his convincing American accent, as he is clearly more focused on trying to combat the unpredictable star-in-the-making.

The moment eventually found its way into the film itself - which just goes to show you how inspired the choice was - and for an actor at such a tender age to boast that kind of scene-commanding confidence, only adds to the impressiveness of Keen's initiative in the situation.

She would steal the show in Jackman's last outing as the titular anti-hero and this unbelievable moment of improvisation will go down in history as the spark that ignited the young star's rise to superstardom.
