DreamWorks Animation (DWA) shareholders can all exhale now.

The Croods, one of just two movies that the company will release this year, is off to a good start at the box office. The tally on its opening weekend box office haul was a cool $45 million.

That strong launch means we probably won't see another big write-down like the one that swamped DreamWorks' results last year.

But there's more for investors to like about The Croods than just solid revenue. Just as important is how much it cost DreamWorks to produce the film. And by that measure the company has already won. This movie was a bargain compared to DreamWorks' last few outings.

The Croods cost just $135 million to make, much cheaper than the $150 million the animator usually shells out to develop a feature. And it plans to drive those costs down even further over the next 18 months -- to around $120 million per film.

It works for games, too
DreamWorks isn't the only company that's trying to do large-scale entertainment on a small-scale budget these days. Game maker Activision Blizzard's (ATVI) newest title is also a move in that direction. Called Hearthstone, the game is a big departure from the company's massive-multiplayer, world-encompassing epics.

While the new game is based on Activision's World of Warcraft hit, it is far less ambitious in scope. This card-building game handles two players at a time, and took a team of just a few developers to put together. That's a far cry from the years of development and hundreds of millions of dollars that Warcraft needed. Still, Activision says the result has been an easy, accessible game that might not be epic in size, but is still "epically engaging."

I think these are smart moves by Activision and DreamWorks. Both companies could stand to rely less on a handful of blockbuster titles and thus risk a single flop that could torpedo the year’s results. And while it makes sense to keep swinging for the fences occasionally, there's no reason that every title has to follow that path.

By driving the cost bar lower, they are free to try some more innovative stuff. And who knows? The next big franchise might even come from one of these less-expensive productions.
