In the 1990s, Wagner introduced himself to a new generation of audiences with his comedic turn as Number 2, the enigmatic and impeccably dressed villain in the Austin Powers trilogy (1997, 1999, 2002), starring opposite Mike Myers. This role showcased his willingness to laugh at his own sophisticated image. Later in his career, he had a recurring role on the sitcom Two and a Half Men (2007–2008) and a long-running guest arc as Anthony DiNozzo Sr. on the hit procedural NCIS (2010–2019), appearing alongside his real-life friend Mark Harmon.
