2) They both make their entrances from bright lights, and both descend flights of steps (well, Siobhan's is a flight; Harry's is like, one or two). A basin of water is present in both scenes -- a baptismal bowl in the church, a sponge bath in the space station.
3) Both pull
creepy facial parlor tricks -- she rolls her
eyes back in her head, Exorcist- style; he
grins till his face literally cracks in a
Joker- like rictus.
4) Both Siobhan and Harry are singers in real life -- he's a little bit Broadway, she's a little bit rock 'n roll. (Now there's a duet idea!!)
5) Both, weirdly, were born THE SAME DAY, September 10, making them Virgos! Siobhan's year is 1958, Harry's is 1951.
6) Long stretch: In the 'I Don't Care' video, Marcella Detroit wakes up screaming from NIGHTMARES, under a carved white stone wall that resembles one in the clinic in Sleepwalkers. The IDC video itself seems to be a dream that the whole band is having, since at the end they're dancing around in nightgowns and bathrobes. Siobhan gives a few creepy grins too!
7) In an unaired episode of Sleepwalkers titled 'Passed Perfection', Bruce Greenwood's lead doctor lies in a near-death coma, dreaming he's waiting at a train station. As a bright light spills down the tracks, he sees a figure coming toward him -- who turns out to be the Smiling Man. Bruce's character is resuscitated just in time. I'll leave you to draw your own conclusions there!!
8) Oh, let's see those lovely horrific leers one more time. :)9) Harry: Born in
Germany.
Siobhan: Banned in Germany.
("Stay"'s video was considered
blasphemous.)
