  We construct a Riemannian metric $g$ on $\mathbb{R}^4$ (arbitrarily close to
the euclidean one) and a smooth simple closed curve $\Gamma\subset \mathbb R^4$
such that the unique area minimizing surface spanned by $\Gamma$ has infinite
topology. Furthermore the metric is almost K\"ahler and the area minimizing
surface is calibrated.
