Stars of Breaking Bad and Better Call Saul have remembered their “dear friend and dynamic human” Mark Margolis following his death at the age of 83. Bryan Cranston, Bob Odenkirk, Giancarlo Esposito and Dean Norris were among those paying tribute to the actor, who played the villainous Hector Salamanca. Margolis first appeared in Breaking Bad as a wheelchair bound Salamanca, communicating menacingly with a bell, before reprising a younger version of the role for the AMC spinoff Better Call Saul.
