%X We study numerically the effect of thermal fluctuations and of variable fluid-substrate interactions on the spon-taneous dewetting of thin liquid films. To this aim, we use a recently developed lattice Boltzmann method for thinliquid film flows, equipped with a properly devised stochastic term. While it is known that thermal fluctuationsyield shorter rupture times, we show that this is a general feature of hydrophilic substrates, irrespective of thecontact angle θ . The ratio between deterministic and stochastic rupture times, though, decreases with θ . Finally,we discuss the case of fluctuating thin film dewetting on chemically patterned substrates and its dependence onthe form of the wettability gradients.
