What makes a great actor? Charisma? Believability? Acting range, the ability to play all sorts of roles? The actor himself or herself being completely different than the person they are portraying?
Probably parts of all those things. And that's where this hypothesis comes in, and it is thus:
Tiffani Amber Thiessen is the greatest actress of her generation.
Now calm down, just cool it. Before you jump all over this theory that just blew your God Damn mind, hear me out.
Sadly, I wasn't able to fully research this and back it up with overwhelming evidence, but please bare with me because I think it is both important and really important.
I had a break from work the past 2 months. In that time I had a regular "not working" routine. In the morning, I would watch 2 hours worth of Saved by the Bell. In the afternoon, I would watch at least an hour of Beverly Hills 90210.
As you know, Tiffani Amber Thiessen is in both of these programs. In Saved by the Bell, she plays the character of plucky, cheerleader, home coming queen and all around good girl, Kelly Kapowski. In 90210, she is scheming, marijuana smoking, money grubbing, club entrepreneur, scheming (she schemes a lot!) Valerie Malone.
As I would watch both of these shows every single day, I came to a realization: I didn't recognize that this actress named Tiffani Amber Thiessen was in both shows. Why? Because the characters of Kelly Kapowski and Valerie Malone are totally and completely different people.
Now, I recognize that perhaps the body changing breast augmentation helps play a part in this. But it is more, it is much, much more.
Tiffani, it's almost impossible to believe someone named Tiffani is a great actor, but she completely immerses herself in both roles, and does it so completely that the person she is underneath is unrecognizable. She is Valerie Malone, and in Valerie Malone, I see no Kelly Kapowski and vice versa.
I have no idea who Tiffani Amber Thiessen is in real life. Let's use 90210 as an example real quick. Shannen Doherty was supposed to be the good girl from Minnesota. Jennie Garth was the rich bitch from Beverly Hills. But over the course of the series, things changed.
The producers of the show could not contain Doherty's true nature, and it was clear to the world that she was pure evil. Same goes for Garth, her character started to become the nice, charity worker girl, because that's who she really is.
But Valerie Malone? A crazy person, all the way through. And Kelly Kapowski? 100% sweetness.
Thiessen/Streep is like the Lebron/Durant debate, I don't know who is better at this point.
