Topic Challenge: Paul Walker and his films [completed]

Question

Last week saw the release of Furious 7, the newest installment in the Fast & Furious franchise and the last film featuring the late Paul Walker. So we're starting a new weekly topic challenge from 2015-04-06 00:00 UTC to 2015-04-12 23:00 UTC asking for any kind of question about Paul Walker and the films he starred in.¹

^{(The original suggestion was about a Fast & Furious challenge. But given that this is definitely not the last big-franchise movie this year and that the interest into this movie doesn't seem so high yet, I thought it a better idea to broaden the scope a little, concentrating on the whole work of a late actor who has always enjoyed his role in that franchise.)}

Once the challenge is over, we'll tally the results and winners (by question votes) here. Also don't forget to suggest and vote for new topics for our next possible challenge.

Answer 1

The challenge is over and the only and thus top-voted question (with a score of amazing 0 and ~50 views) was asked by Tushar, which makes him the winner of this challenge:

1. When did Letty regain her memories?
