Is it considered disbelief for a Muslim to perform the movements of prayer and the opening takbeer with the intention of deceiving others, without the intention of prayer or ablution, while knowing that this is forbidden?

Looking at pornographic films and masturbation are forbidden. Whoever prays while in a state of janabah (definition) (major ritual impurity) has committed a grave sin. He must repent and seek forgiveness, and repeat the obligatory prayers after purifying himself, because ritual purity is a condition for the validity of prayer. Allah Almighty says: "And if you are in a state of janabah, then purify yourselves." The Messenger of Allah, peace and blessings be upon him, said: "Allah does not accept a prayer without purification." It is not permissible to abandon purification under the pretext of embarrassment from people.
