I'm searching for movie I watched maybe 10 years ago. I don't remember its name, but in the end, a car explodes and the main character is believed to be dead, but it's just to throw off those who tries to kill him and his family. I think it involves some kind of training phase where he learns to be someone else, but I'm not sure. In general there is a lot of twists. Genre: Thriller, from US
Protagonist Annibal Ramirez (played by Quinn) is trained to masquerade the terrorist Carlos the Jackal.
At the end of the movie CIA fakes the deaths of Ramirez and his family in car explosion, so they may live safely with a new identity.
Could it be Eraser with Arnold Schwarzenegger?
Arnold plays a guy who "erases" people who are in a witness protection program and who's lives are in danger. At the beginning of the movie, he saves an informants life by changing his identity with that of a dead man, destroying this guys home/safe house with the dead guys corpse in there to make it look like the informant died.
At the end (without giving much away) Arnold's car blows up in front of a courthouse with all the people who wanted him dead watching. Everyone thinks he is dead, but he isn't.
