Marty Lang appeared in the same episode as Hank Wheldon during season two of Miami Vice. He was a former Metro-Dade Vice detective and used to be Wheldon’s partner. The two helped bring down the prominent drug dealer, Tony Arcaro, after three years of failed attempts.
It’s believed that Marty Lang unlawfully killed Arcaro after failing to jail him in legal ways for so long. The character ended up being incarcerated for the crime and disappeared from Miami Vice, but not before leaving a big impression on the show’s viewers.
Bruce McGill As Hank Wheldon
Retired Metro-Dade officer Henry "Hank" Weldon started out as a cop but found himself promoted to detective after helping incarcerated the drug trafficker, Tony Arcaro. He appeared in the episode "Out Where the Buses Don't Run", that premiered on October 18, 1985, during the second season of the show.
Hank Wheldon was quite brash, aggressive and hot-headed, which is why he was perfectly cast when Bruce McGill was chosen for the role. The actor seems to have a knack for burly and offensive characters and left quite an impression on us long after his short role had ended.
Bruce McGill– After the show
Right after his role on Miami Vice, Bruce McGill found himself portraying Jack Dalton, a good friend of MacGyver's who always seems to get the two in trouble thanks to his love of get-rich-quick schemes. He is best known for acting in some of director Michael Mann's films, including The Insider, Ali, and Collateral. The actor is also a fantastic narrator and made various ads for the Republican Party during the 2016 presidential election.
Bruce McGill recently appeared in a 2019 drama film called The Best of Enemies alongside Sam Rockwell and Taraji P. Henson. He also appeared in a small-time film called Waiting Game, which landed him an award for Best Actor at the Pasadena International Film Festival. The actor's best role to date is arguable as former U.S. Secretary of War Edwin M. Stanton in the seven Golden Globe Awards winner film, Lincoln.
David Strathairn– After the show
After his role in Miami Vice, actor David Strathairn continued to appear in many films and TV shows over the years. He managed to snag an Emmy and a Golden Globe nomination for his role as Dr. Carlock in 2010's biographical drama film Temple Grandin. Although Strathairn has a very large list of roles in films, he never really managed to find himself as a lead actor and was mostly typecast as a supporting actor.
David Strathairn is mostly recognized today for his role as CIA Deputy Director Noah Vosen in the 2007 film The Bourne Ultimatum and its sequel, 2012's The Bourne Legacy. He almost won a Screen Actors Guild Award for Outstanding Performance by a Cast in a Motion Picture for playing the Secretary of State William H. Seward in Steven Spielberg's Lincoln, but ultimately lost to another actor.
Liam Neeson As Sean Carroon
Almost nobody remembers that Liam Neeson actually had a role in Miami Vice way before he became famous. The actor played Sean Carroon, a member of Provos, the provisional wing of the Irish Republican Army. He appeared in the show's opening episode of season three, titled "When Irish Eyes Are Crying". The character eventually died at the end of the episode, after being shot by Gina Calabrese, one of the show's main characters.
The character was a semi-psychopathic killer and died in a very fitting way by being shot after refusing Gina's desperate pleads for him to disarm his weapon. Who could have predicted that the guy who played him would end up becoming the great Liam Neeson, one of the world’s most prominent actors?
