Top 10 Best Actors and Actresses in a Sci-fi TV Show

The Top Ten
Jared Padalecki - Supernatural Jared Tristan Padalecki is an American actor. He is best known for playing Sam Winchester is the CW series Supernatural. He grew up in Texas and rose to fame in the early 2000s after appearing on the television series Gilmore Girls as well as such films as New York Minute and House of Wax.

I'd like to see Jared get the recognition he deserves. Walker is going to grow his fan base so much that he's going to reach another level of stardom. I hope he'll still be able to be out in his hometown without getting chased by his fans.

Jared is special, and I hope the network realizes just how extraordinary he is. If he gets film offers, I really hope the network will work with the film studios to allow time for Jared to pursue outside projects.

I don't think aging will affect his popularity at all, and someday I hope to see him get nominated for an Academy Award.

Jensen Ackles - Supernatural Jensen Ross Ackles is an American actor and director. He is mostly known for his role as Dean Winchester on the CW fantasy series Supernatural. He is also known for his roles in television as Eric Brady in Days of Our Lives, which earned him several Daytime Emmy Award nominations, as well as Alec/X5-494... read more

Right where he belongs! On top!

Jensen is a great actor, but unfortunately, he is not appreciated as much as he should be. I'm not being biased, but Jensen Ackles' acting skills are just perfect. Nobody can possibly do better than him. He's a hallmark!

And, oh, his pretty face is just perfection! Plus, his voice is so out-of-this-world! I don't think anybody even comes near Jensen in any regard.

Jensen is caring and generous. He's charismatic, and he really shows his love for his fans. He values friendship and is dedicated to portraying Dean Winchester in a way that we love. I could never imagine Dean being brought to life by anyone else.

David Tennant - Doctor Who David Tennant is a Scottish actor known for his roles as the Tenth Doctor in the British television series Doctor Who, Alec Hardy in Broadchurch, Giacomo Casanova in the TV serial Casanova, Kilgrave in Jessica Jones, and Barty Crouch, Jr. in the Harry Potter movie series.

Charming from the first moments, his character is both dramatic and hilarious. He's so sincere and noble that he takes you through all the adventures and hardships, and you really stick with him to the very end.

David Tennant ROCKS! He is the best incarnation of the best character in the best show ever!

Someone who really knows how to act. He can make us cry and laugh within 30 seconds.

The heart, the soul, and the mind of The X-Files. I love seeing how he deals with his boss, Skinner. His girlfriend, Scully. And his friends, The Lone Gunmen.

He is the bravest man in the world.

The most iconic character in the entire world. The only one who never changed (unlike his partner). He has always been the same perfect hero from the first episode until the end.
