Imax Corp. and Walt Disney Studios said Wednesday that they have agreed on a deal to release three more 3D movies to Imax theaters next year. The movies are "Mars Needs Moms," which is scheduled to be released next March; "Pirates of the Caribbean: On Stranger Tides," set for release in May; and "Cars 2," which is scheduled to be released next June.

Disney had previously agreed to release five 3D films with Imax. Many moviegoers experienced Imax for the first time when they saw "Avatar," which in turn boosted both the number of the company's new repeat customers and demand for 3D films in huge-screen format. Imax shares fell 14 cents to $16.16 in afternoon trading, while shares of Walt Disney Co. rose 2 cents to $34.37.
