I took Season 1 photos of the TNG cast. I ran them through celebrity lookalike matching at MyHeritage.com...
And I went with the youngest match. (This is just for laughs.)
Jean-Luc Picard - David Boreanaz (Angel, Bones)
William T. Riker - Kevin Zegers (Dawn of the Dead, Air Bud)
Deanna Troi - Anna Paquin (X-Men, The Piano, True Blood)
Data - Jesse Bradford (Flags For Our Fathers, Bring It On, Romeo+Juliet)
Dr. Beverly Crusher - Eliza Dushku (Buffy, Dollhouse, Bring It On)
Geordi La Forge - Dule Hill (Psych, The West Wing) Took a BUNCH of tries not to get a woman.
Tasha Yar - Alison Lohman (Drag Me to Hell, Big Fish)
Worf - Oy. Can't get a match who isn't white or female.
