Sony picks up spec script “Invertigo” from Transformers scribe Ehren Kruger and co-writer Bradley Camp. Logline kept under wraps.

Kruger is repped by attorney Jason Sloane.

By my count, this is the 15th spec script to sell in 2012.

Last year at this time, there had been 7 spec sales.

Sales are up 114% year-to-date compared to 2011.
