4/21/09 - I found another!
There are 10 actors/actresses in the LOTR Trilogy that have ties in 13 other "blockbusting" trilogies - who are they, what are the other trilogies (or more) and their roles?
Hugo Weaving (Elrond) LOTR & The Matrix (Mr. Smith)
Orlando Bloom (Legolas) LOTR & Pirates of the Carribean (Will Turner)
Ian McKellan (Gandalf) LOTR & X-Men (Eric Lehnsherr / Magneto)
John Rhys-Davies (Gimli and Treebeard) LOTR & Indiana Jones (Sallah)
** He didn't appear in "The Temple of Doom"
Christopher Lee (Saruman) LOTR & Star Wars (Count Duki / Darth Tyranus)
*** Star Wars II & III (I consider them 2 separate trilogies) - check LOTR:Return of the King EXTENDED version (to consider him in all 3)
Ian Holm (Bilbo) LOTR & the Alien Quadrilogy (Ash)
*** LOTR 1 & 3; Bilbo did not appear in "Two Towers" - He was only in "Alien", the first of the "Quadrilogy". Also interesting, is that Ian played in "Alien" with John Hurt who had just played Aragorn in the first "Lord of the Rings" movie in 1978.
Karl Urban (Eomer) LOTR & The Riddick Trilogy (Vaako) & The Bourne Trilogy (Kirill)
**** If we include Bilbo, we have to include Eomer. LOTR 2 & 3 (Eomer did not appear in "Fellowship of the Ring") - He was in "The Chronicles of Riddick" which is just barely a "trilogy" because there are 2 live action movies (including "Pitch Black") and a third amime movie that sits (chronologically) between the two.
***** He was also in "The Bourne Supremacy" which (at this point) is a trilogy. (thanks for the help on this one).
Cate Blanchett (Galadriel) LOTR & Indiana Jones (Agent Irina Spalko)
****** OK, this is gettin crazy - Cate is in all three LOTR movies and she is in the new Indiana Jones movie "Indiana Jones and the Kingdom of the Crystal Skull"
Brad Dourif (Grima Wormtounge) LOTR & Alien Quadrilogy (Dr. Jonathan Gediman) & Child's Play (Charles Lee Ray/Chucky) & The Exorcist (James Veranum)
******* OK, stay with me...
Brad is a busy guy... He is in the last two LOTR movies (extended versions), Alien Resurrection, All three "Child's Play" moves and The Exorcist III...wow.
Elijah Wood (Frodo Baggins) LOTR & Back to the Future Trilogy ("The Video Game Boy)
******* Ok, Obviously, Elijah is in all three LOTR movies, he is in Back to the Future II - even though it's a small part (actually, his first). http://my.spill.com/profiles/blogs/child-actors-then-and-now
