Supposedly Watto’s accent is ‘Italian’
0_O
There are a few Mario-like stereotypical intonations in Watto’s speech. Even his word endings can come off as stereotypically Italian at times.
The real problem with the PT accents is that there’s only so many sounds and intonations to take from, so it’s bound to resemble something.
I’m sure Ahmed Best added some of his own to Jar Jar (or at least something he was familiar with). Then Brian Blessed interpreted Best’s accent with his own deeper voice, which results in intonations and inflections that can come off as cartoonishly Jamaican at times. Gen. Tarpals actually sounds Japanese at times. His tone of voice and inflections sound very Samurai-like some sentences, then suddenly the dialogue takes on certain South African-like sounds. Seriously, listen to Tarpals first few lines in TPM. It’s a hodgepodge of several accents.
