  We consider the asymptotic expansion of the Wright function
\[W_{\lambda,\mu}(z)=\sum_{n=0}^\infty\frac{z^n}{n! \Gamma(\lambda
n+\mu)}\qquad (\lambda>-1)\] for large (positive and negative) variable and
large parameter $\mu$. The analysis is based on use of the method of steepest
descents applied to a suitable integral representation and, in part,
complements the recent work of Ansari and Askari. Numerical results are
presented to illustrate the accuracy of the different expansions obtained.
