If you're willing to put forth a little effort, find pics on the internet of the actors/actresses you want.

Then using and art program such as gimp, or photoshop, stretch and paste the image over an existing texture file (but be sure to save the original file in another location).

save the file in your textures directory and  "Voila! " instant actor!

 You can then morph the head to the shape of your person for a much better effect!
