What was so terrible about Martin Sheen? He seemed to come across as convincing as the once rejected lover of Viveca's who now seeks his revenge by not giving her the formula.

I suppose I will always think positively of Martin Sheen ever since seeing his terrific portrayal of John F. Kennedy in the 1983 mini-series "Kennedy."

I would agree that this is not the finest hour of the series, but I don't think that it is necessarily the worst ever. I rather enjoyed Vera Miles performance in this episode.

We all have our personal bete noire's in the Columbo series, but I will not rest easy until I convince everyone that Murder, a self portrait is THE worst episode.

However I think the final clue in "Lovely but Lethal" is quite a clever one
