Actor-screenwriter Tyler Perry testified in a copyright infringement lawsuit in Marshall, Texas, that he didn't steal material from a woman's play for his blockbuster movie "Diary of a Mad Black Woman."

Donna West of Fort Worth is suing Perry in federal court over a script titled "Fantasy of a Black Woman" based primarily on her own experiences.

She wants a jury to award her family all the profits made from the 2005 film, which earned some $50 million.

West's lawyer, Aubrey "Nick" Pittman, grilled Perry with questions ranging from if he possessed an original copy of his script of "Diary of A Mad Black Woman" to whether certain ideas he used in his film were original. Perry testified he "never stole anything from anybody -- never."

He also denied copying anything.

Testimony is scheduled to resume today.
