Heath Ledger or Keith Ledger
Who is the actor was dead on Tuesday afternoon in Manhattan? Heath Ledger or Keith Ledger? After you read this post, you will know the truth. Several peoples who use internet for getting this information was made mistake.
You knew about it. 
On wiki Heath Ledger was described like here.
Heathcliff Andrew Ledger (April 4, 1979 – January 22, 2008) was an Academy Award-nominated Australian actor. After appearing in television roles during the 1990s, Ledger developed a Hollywood career. He starred in both critical and financial successes, including The Patriot, Monster’s Ball, and Brokeback Mountain, and completed the role of The Joker in the forthcoming The Dark Knight. Ledger died in New York City on January 22, 2008.
Keith Ledger, who is surely unrelated to Heath is listed in the IMDB as one of the miscellanious crew as designers of the video game “Warzone 2100.” There is no other information on him online.
Machinist called it’s a ferocious googling. Heath Ledger and Keith Ledger are different person. Keith ledger? You mean Heath? and yes, he is dead.
I’m trying to understand the point you are making in this post about Heath Ledger. Was someone saying that Keith Ledger and Heathcliff Andrew Ledger was the same person? I never heard of Keith Ledger before this post. I’m guessing that someone had a misundestanding of who died back in January. I heard that Heath’s daughter was given his estate this week.
