Just as I wondered a couple of years ago about Mark Harmon & Gregory Smith, I noticed recently a remarkable resemblance between Jewel Staite (known as Dr Jennifer Keller in Stargate Atlantis) and Rupert Grint (known as Ron Weasley in the Harry Potter series).
It’s (of course!) not the bodies, but more the facial expressions.
I like to watch Stargate Atlantis, it is my favorite TV show.
