Shortly after the announcement that Stephen Amell will be playing the role of Casey Jones in the TMNT movie sequel, Half Shell, amateur set pictures popped up online of Amell filming in his Casey Jones costume. This prompted Paramount/Nickelodeon to release an official picture of Amell.
You have to do a bit of squinting, but you can read the name "EASTMAN" on the hockey stick he's holding.
Also spotted recently was the one-and-only Judith Hoag, shooting street scenes with Megan Fox (April O'Neil) and Will Arnett (Vern Fenwick). Of course, Hoag was the original April O'Neil in the first TMNT movie from 1990. Although she declined working in the sequels to that film, she remains for many the definitive April O'Neil. While her role in the new movie isn't known, it is definitely a nice acknowledgment to the past.
