The real Luis Miguel has a brief cameo in the first episode as a guest during the party scene.
Diego Boneta is the ex-boyfriend of Michelle Salas, Luis Miguel's beautiful elder daughter.
Diego Boneta spent a year getting his singing voice to sound like Luis Miguel's; he also had surgery to create a little gap in his front teeth and had regular tanning sessions to recreate the superstar's 1980s and 1990s look.
The casting of internet star Juanpa Zurita as Alex Gallego, the younger brother of Luis Miguel, was met with mixed reactions. Some thought Zurita, who had not acted in such a big production before, would not live up to the series. Ultimately he helped garner a new generation of fans to the show.
Oscar Jaenada (who plays Luis Rey) declared he wasn't fond of Luis Miguel's music, and he only took the role for the character of Luis Rey, as he found him compelling and thought it would be interesting to study why he acted the way he did.
