In Assassination, a routine political thriller directed by Peter Hunt, Jay Hillion (Charles Bronson) is a secret service agent assigned to protect First Lady Lara Royce Craig (Jill Ireland). Lara hates Hillion and tries to get away from him but finds she needs him when her life is threatened by a series of assassination attempts which may have originated from the White House. This routine actioner has little to offer that is new or different, but it tells its tale at a good pace and has some nice location photography. Charles Bronson gives his usual steely performance, while Jill Ireland is more sympathetic as the First Lady who likes her independence but must learn to trust a man she detests. This film, while routine and somewhat predictable will be enjoyed by Bronson fans.
