Day-Lewis plays an oil magnate in "There Will be Blood" by US director Paul Thomas Anderson that will have its international premiere at the February 7-17 festival. It is based on the novel "Oil!" by Upton Sinclair.
Anderson won the festival's Golden Bear top prize for "Magnolia", starring Tom Cruise, in 2000.
Other films in the partial line-up announced on Monday include Chinese director Wang Xiaoshuai's "Zou You" (In Love We Trust) about a mother's bid to save her firstborn child from cancer.
Wang won the Silver Bear for the film "Beijing Bicycle" in 2001.
Wajda will bring "Katyn", a film about the massacre of thousands of Polish officers and intellectuals by Soviet troops in 1940, to the festival. His father was among the victims.
The film will screen out of competition.
The full line-up of the film festival, one of the three biggest in Europe, will be announced in January.
