First I watched Bruce Willis in his blockbuster action thriller Die Hard. He played role of a tough cop. He played role of a detective in comedy crime The Last Boy Scout. Then again he played same role in another mystery crime Striking Distance.
Bruce Willis played role of a FBI agent in crime drama Mercury Rising. Again he played role of a cop in Hollywood film Hostage. Bruce Willis appeared as a cop in blockbuster Sin City. He’s detective in 16 Blocks. Again he played role a FBI agent in sci-fi thriller Surrogates.
Also he worked as a cop in Cop Out and Fire With Fire. In some other movies he appeared as a CIA agent too such as Red. That’s my personal observation so it can be wrong but I think so I wrote. Thanks for reading.
