  We review the results for the Sudakov form factor in N=4 super Yang-Mills
theory up to the three-loop level. At each loop order, the form factor is
expressed as a linear combination of only a handful scalar integrals, with
small integer coefficients. Working in dimensional regularisation, the
expansion coefficients of each integral exhibit homogeneous transcendentality
in the Riemann zeta-function. We find that the logarithm of the form factor
reproduces the correct values of the cusp and collinear anomalous dimensions.
Moreover, the form factor in N=4 super Yang-Mills can be related to the leading
transcendentality pieces of the QCD quark and gluon form factor. Finally, we
comment briefly on the ultraviolet properties of the N=4 form factor in D>4
dimensions.
