What is with the 70 minutes running time? Is that a DC AU standard? If so, that's really stupid. At least make it an hour and a half. Many (many, if not all) of the most successful kids movies have been in the 1.5 hour range. If it's good, it will hold their attention.
These are not kids movies
. These are DTVs
. A quick check at Disney DTV sequels shows approximately 70 minute run times too. The fact is you just can't make enough money on a DTV to justify the cost of a 90 minute production.
