10 TV Show Mistakes Directors Left In Because The Acting Was Too Good

A far more literal misstep once saw the cast of That '70s Show having to expertly think on their feet.

With Ashton Kutcher's Kelso not exactly being known as the brightest personality in the world, the visual of the goofball flying across a sofa and almost completely wiping out during the events of Season One's The Best Christmas Ever didn't feel all that out of character.

In reality though, this was actually a case of Kutcher completely misjudging his landing for real, and just about keeping it together long enough to get through the subsequent moment opposite Lisa Robin Kelly's Laurie.

The end result left the studio audience howling with laughter, and Kelly herself legitimately struggling to keep a straight face as Kutcher did all he could to compose himself.

Had any other character found themselves at the centre of such a potentially disastrous botch, there's a good chance the scene would've been taken back for another attempt.

But with this physical blunder being one that seemed comically in-character for Kelso and subsequently making the awkward moment even more hilarious than it looked on paper, the team behind the show felt it deserved to stay in the finished article.
