A new service launched late yesterday promises to make streaming your favorite purchased movies easier by putting them all in one place. The new free app Movies Anywhere acts like a digital locker for the movies you've paid for through various online retailers, including Amazon Video, Google Play, iTunes, and Vudu. Signing up for a Movies Anywhere account gives you access to the digital locker, which you can then populate with purchased or redeemed movies by logging in to the accounts you have with those online retailers.
