‘Arrow’ Adds Colin Donnell as Tommy Merlyn

CW’s The Arrow just updated its cast list today to include Colin Donnell as title hero’s best friend Tommy Merlyn. In this incarnation, Merlyn is one of Oliver Queen’s fellow “trustafarian” friends from his past, but notices that Oliver returns to the city a changed man. Whether that Tommy will become the Green Arrow’s arch-rival Merlyn in this series remains to be seen.
