Mars Attacks!
Tim Burton’s comedy sci-fi, Mars Attacks! had quite the cast. Everyone from Jack Nicholson and Natalie Portman to Pierce Brosnan and Sarah Jessica Parker in the movie. However, it was Frank Welker that added in what became a signature of the film. This voice actor had no direction in the script about what the Martians would say so he invented the “ack! ack! ack!” barking noise.
Tarzan The Ape Man
We’re taking you back not to the 1981 version with Bo Derek but all the way to the 1932 version. That was the film starring Johnny Weissmuller and Maureen O’Sullivan. Anyway, during the film, the script just said Tarzan would call to his jungle friends. Weissmuller was an excellent yodeler and thus, he invented what became Tarzan’s signature echoing cry!
