'The Smurfs' Movie -- La La Lalalala La La La La Lawsuit

The people behind the new "Smurfs" movie really blue it -- at least according to a construction worker, who says an on-set accident left him all smurfed up ... and now he's suing for $15 million.

Ryan Rodriguez filed the lawsuit against Columbia Pictures, Sony Entertainment, famed toy store FAO Schwarz, and more.

According to the lawsuit, FAO Schwarz in NYC was leased by Sony and Columbia as a shooting location back in May 2010. (For you saps who've never been, FAO Schwarz is the place where Tom Hanks played the giant floor piano in "Big")

Now the sad part -- around May 20th, Ryan claims he fell off scaffolding inside FAO while doing construction on the set and "seriously and permanently" injured himself. He says the accident pretty much ruined his life and he hasn't been able to work like he's used to.

Ryan claims Columbia, Sony, FAO Schwarz and the other defendants are responsible for the accident -- by failing to provide a safe place to work -- and now, he wants $15 million in damages.
