This is JLA Adventures: Trapped in Time, an all-new original animated movie starring the Justice League that debuts exclusively at United States Target stores on January 21st! If you read the write-up on World'sFinestOnline.com, you'll see that, for some unfathomable reason, Warner Bros. is putting this out as a "stealth release", in that they are doing absolutely no advance promotion: no commercials, no preview copies to media outlets, not even a trailer! Consequently, there's very little info on the title--IMDB doesn't even have a page for it yet.
The write up at the above link says it features "The traditional Justice League line-up", and indeed you can see Aquaman pictured on the box art. So I guess the next time I'm shopping at Target, I'll be swinging by the entertainment section to give this a look.
If anyone gets this movie and wants to review it for the Shrine, drop me a line and we'll make arrangements. All us Aqua-Fans need to know if the Sea King makes an appearance!
