José María Iglesias was a Mexican voice actor who worked on several Muppet dubs, notably as the Spanish voice of Kermit the Frog (Rana René). He began his Muppet association on Plaza Sésamo, first dubbing Herry Monster (Greñaldo) and other monsters. By the time of The Muppet Show (El show de los Muppets), Iglesias was cast as Kermit and took over the role on the Plaza as well (from original voice Salvador Nájar), continuing into the movie dubs. He served as dubbing director for the original Mexican dub of The Dark Crystal.
