Parallel with Bridge Over the River Kwai 1957

Rating: 8/10 (17 November 2006)

Recently watched this again and noticed a parallel with "A bridge over the River Kwai" 1957.
After the scene where Mace Windu is fighting the Chancellor Palpatine Anakin cuts of Windu's arm.
Suddenly he says "What have I done?" The exact same phrase Col. Nicholson uses after stopping the destruction of the japanesse bridge in the 57 film.
Ewan McGregor studied Alec Guiness who played the Nicholson role, another connection.
Anyone else notice any links to other films?
