[Speaking French] Wonderful.
[Speaking French] I will tell you.
The joke is three layers deep. The Basterds are supposed to be Italian filmmakers, but they speak with thick American accents mangling basic Italian phrases. The German officer (also undercover) says in German: “These Italians certainly have a strange accent.” Another German replies: “They are from the mountains.” The subtitles translate every German mutter about how unconvincing they are. The comedy shifts from broad slapstick to sharp linguistic humor. Without the subtitles, you laugh at Pitt. With subtitles, you laugh at the Germans trying to rationalize the nonsense.
