The Bourne Identity, 2002 film starring Franka Potente, Matt Damon, Chris Cooper and more. This was the start to the Bourne series which now I believe is 5 films, though I shouldn’t count The Bourne Legacy because it did not include Damon. (He makes the film)
After being rescued by fishermen and his injuries fixed a man (Damon) sets out to find who he is. At this point he has total amnesia with only the odd flashback to his memory. His journey leads him to many cities and slowly discovers that he may have been an assassin. The company he works for also gets wind of his location and begins a massive manhunt to kill him off before everything becomes public.
Great action film, the casting was spot on here, from Damon all the way to the top brass at the CIA (Brian Cox) This was a well made film, lots of car chases and fighting.
