Bob Hoskins makes an unusually genial Professor Challenger, far less of a bully than Doyle's character, but his slightly stereotyped companions are nicely filled out by a solid cast. James Fox is Challenger's more timid but still covertly adventurous rival, Tom Ward is the moustachioed big game hunter who faces an Allosaurus with an elephant gun, and Matthew Rhys plays the tagalong reporter hoping to impress his faithless fiancée.
