They actually had Mandalorian font in the background screen when Viszla was talking with Dooku.
When the one Death Watch, who jumped from the balcony, was dying, they actually had him speaking in Mando'a. He even uses the phrase "Darasuum Kote," which is Mando'a for "Eternal Glory," made popular in the song from the Republic Commando games.

Scenes with Mandalorians: the holocron scene with Dooku
Two Mandalorians kicking around Obi-Wan in an industrial building
Obi-Wan upside-down in a yellow container; rescue attempt by the Dutchess; two Mandalorians holding her arms; Obi-Wan breaking out and, again, kicking the Mandalorians...
Group of Mandalorians firing guns at Obi-Wan and company; three ordered to "stop him" use their jetpacks; one gets knocked off by a blaster
Governor Pre Vizsla walking up, says "failure," and shoots the injured Mandalorian; takes his helmet off, recognized as the governor: "For generations, my ancestors fought proudly as warriors against you Jedi. And now that woman tarnishes the very name Mandalorian. Defend her if you will. (Throws lightsaber.) This lightsaber [referencing a black lightsaber] was stolen from your Jedi Temple by my ancestors during the fall of the Old Republic. Since then, many Jedi have died upon its blade. Prepare yourself to join them."
Fight, including a moment where Pre uses his jetpack. "Warriors, finish him." They fire three jetpack rockets, which all miss, but have some kind of tracking which corners Obi-Wan in the industrial building's basement.
"Should we go after him, sir?" said by a Mandalorian with a Jango-esque accent. "No. There's no time. Don't worry. We'll catch up with the Dutchess."
