The Philadelphia Story - S4-E26
Question: Is this the first time Will went back to Philadelphia?
Answer: As stated previously, Will returned from spending the summer in Philly at the beginning of s03e01. But this is the first time the audience sees Will going back to Philadelphia.
Answer: No, it's not Whoopi Goldberg herself, just like that's not Prince or Ray Charles. The limo is filled with celebrity impersonators, but they're all uncredited and I could find out who played them.
