A Manhattan man is ticked off that his director son — whose most famous movie dramatized Lyme disease — is trying to steal a building out from under him, a $5 million suit says.

Derick Martini, 38, made his name in Hollywood in 2009 with “Lymelife.” His father, Frederick, claims Derick went behind his back to take half-ownership of the building.

Frederick Martini, 66, alleges Derick created a fake deed.
