Sorry, but that's not exactly true. Liam Neeson portrayed the Irish freedom fighter Michael Collins in the 1996 Movie of the same name. Collins was shot by a republican Sniper during the Irish Civil War in 1922. I'm not exactly an expert on Liam Neeson movies altogether, so I might miss further examples, but I know this one. But any meme with Darth Maul on it is great (Ray Park did a tremendous job playing this badass duelist).
