Blast from the Past is a nice romcom from the late 90s starring Brendan Fraser and Alicia Silverstone. And although it is quite entertaining, the actual highlight of the movie are Christopher Walken and Sissy Spacek, no doubt. For that reason, it is a real shame that their parts are rather small resp. smaller in the International Version because outside the US, more than 9 minutes are cut. Only in the US, the movie is complete.

All in all, the International Version lacks 25 scenes with a total length of 9:16 minutes.

Compared are the International Version (German TV broadcast) and the uncut US Theatrical Version (US Blu-ray).

Helen has her doubts it might work out.
