A few years ago, I watched and reviewed every movie in his filmography, no matter how small the part, from the 70s through the 90s in order. It was fun.
The few that I hadn't seen were very forgettable. The worst was easily
Beretta's Island. Arnie is in it for only 10 minutes at the beginning. It stars his best friend and weightlifting buddy Franco Columbu, who wanted to try acting like Arnie and needed his involvement to get financing and sell videocassettes. If you think that Arnie's acting is bad, you should see Franco's. No how no way this guy would've ever gotten to star in a movie if not for Arnie's pull at the peak of his stardom (1993).
Most movies that I'd seen were no different than I remembered them. Eraser is one of the few (maybe the only) that was less enjoyable than I remembered. Maybe it's partly because it's relatively serious, but it didn't age well for me. On the other hand, True Lies surprised me with just how well it aged. I probably shouldn't have been because it's James Cameron, but I loved it just as I did in 1994.
